 ## Interacting with the IDE
 
+### IDE_Morph.prototype.getScenes()
+The getScenes() method returns an array with the names of all scenes in the projects. The minimum number of elements is 1, since there is always at least one scene per project. The scene names are unique strings within the array. Note that the empty string ('') is a valid scene identifier.

+#### syntax
+    ide.getScenes();
+
+#### return value
+an Array of Strings, minimum length 1
+
+
+### IDE_Morph.prototype.getCurrentScene()
+The getCurrentScene() method returns a string representing the name of the currently active scene in the project. If the scene is unnamed and empty string is returned.
+
+#### syntax
+    ide.getCurrentScene();
+
+#### return value
+a String, can be an empty String
+
+
+### IDE_Morph.prototype.switchTo()
+The switchTo() method displays the specified scene. It suspends all processes and clones of the previously active scene and passes control to the new scene.

+#### parameters
+* sceneName
+    - string, the name of the scene to be activated

+### IDE_Morph.prototype.stop()
+The stop() method immediately terminates all currently running threads in the active scene and removes all temporary clones. It does not trigger a "When I am stopped" event.
+
+#### syntax

 ### IDE_Morph.prototype.broadcast()
 The broadcast() method triggers all scripts whose hat block listens to the specified message. An optional callback can be added to be run after all triggered scripts have terminated.

 There is a special case of display alignment for pictures with a list as the shown result of an expression.  These pictures take a lot of vertical space, so in some cases they are aligned right, with a text paragraph in a text box to the left of the speech balloon but overlapping horizontally with the actual block.  See page 38 for two examples.
 
-Pictures in line with text (typically a single block):  Text Wrap > Tight, then Format Picture > Layout > Advanced left space to zero, right space to 0.6 inches.  Then you can drag the block where it belongs in the text, but the fine positioning will require the cursor arrow keys.  Put spaces in the text left or right of the picture where syntactically appropriate, i.e., where you'd put a space left or right of a word.  To see why pictures taller than a single block are problematic in line, look at the second paragraph on page 7.  It's layed out correctly, with respect to its meaning, but it /looks/ screwy.  I should fix it.

 Writing style:  Use exclamation points (other than in the name "Snap!") very sparingly; they should indicate danger, not enthusiasm.  Absolutely do not suggest that something is "fun" or "interesting," etc.  (But "more interesting" is okay when it means that you are giving a first, trivial example followed by an example that actually does something useful.)

These pictures will be out of place if the text on that page changes.  To fix them, move the picture out of the way; delete the extra spaces (keeping one before and/or one after where the picture belongs, depending on nearby punctuation; set the picture's "Wrap Text" to "Tight"; then position the picture where it belongs.  The last little bit of positioning should be done with the cursor arrow keys rather than with the mouse.  Finally, go to
 	Format Picture > Layout > Advanced > Text Wrapping
-and change the left distance to 0 and the right distance to 0.6 inches.)
+and change the left distance to 0 and the right distance to 0.06 inches.)
 
 7.  If you made changes, save again, then go back to step 2.

 iteration-composition.xml	Iteration, composition	Traditional loop constructs (while, until, etc.) plus the Lisp "named let" (a generalization of FOR) plus functional iteration (repeated invocation of a function) and function composition.
 list-utilities.xml	List utilities	Some standard functions on lists (reverse, sort, etc.)
 colors.xml	Colors and Crayons	Incorporates the former crayon and set RGB libraries.  Implements fair hues (more orange, less green, adds brown) and a linear color scale including grayscale and fair-hue-based shades.
+crayons.xml	Crayons	Just the crayons, without the rest of the colors library.  Fast and simple.
 bignumbers.xml	Bignums, rationals, complex #s	The full Scheme numeric tower.  "USE BIGNUMS <True>" to enable.
 cases.xml	Multi-branched conditional	Like "switch" in C-like languages or "cond" in Lisp.  Thanks to Nathan Dinsmore for inventing the idea of a separate block for each branch!
 try-catch.xml	Catch errors	Run a script; if an error happens, instead of stopping the script with a red halo, run another script to handle the error. Also includes a block to cause an error with a message given as input. Also includes a block to create a script variable and give it a value.

 strings.xml	Strings, Multi-line input	Extract substrings of a string in various ways. In general, text inputs allow only a single line.  The MULTILINE block accepts multi-line text input and can be used in text input slots of other blocks.
 apl.xml	APL primitives	Adds features from the APL language supporting hyperblocks.
 stream-tools.xml	Streams (lazy lists)	A variation on the list data type in which each list item isn't computed until it's needed, so you can construct million-item lists without really taking up all that time or memory, or even infinite-sized lists.  (A block that reports all the prime numbers is included as an example.)  See SICP 3.5 for a tutorial.
-bar-charts.xml	Bar charts	Takes a table (typically from a CSV data set) as input and reports a summary of the table grouped by the field in the specified column number.  The remaining three inputs are used only if the field values are numbers, in which case they can be grouped into buckets (e.g., decades, centuries, etc.).  Those three inputs specify the smallest and largest values of interest and, most importantly, the width of a bucket (10 for decades, 100 for centuries).  If the field isn't numeric, leave these three inputs empty or set them to zero.  In that case, each string value of the field is its own bucket, and they appear sorted alphabetically.  The block reports a new table with three columns.  The first column contains the bucket name or smallest number.  The second column contains a nonnegative integer that says how many records in the input table fall into this bucket.  The third column is a subtable containing the actual records from the original table that fall into the bucket.  If your buckets aren't of constant width, or you want to group by some function of more than one field, load the "Frequency Distribution Analysis" library instead.

Snap! will not attempt to compute a result bigger than a few million atomic items.&#xD;⍳(⍳ 9) will work (≈ 3 million atoms) but ⍳(⍳ 10) will give an error.</comment><header></header><code></code><translations></translations><inputs><input type="%n"></input></inputs><script><block s="doIfElse"><block s="reportIsA"><block var="n"/><l><option>list</option></l></block><script><block s="doIfElse"><block s="reportEquals"><custom-block s="rank of $⍴⍴-1-255-255-0 %l"><block var="n"/></custom-block><l>1</l></block><script><block s="doIfElse"><block s="reportListContainsItem"><block var="n"/><l>0</l></block><script><block s="doReport"><block s="reportReshape"><block s="reportNewList"><list></list></block><block s="reportListItem"><block s="reportNumbers"><l>1</l><block s="reportDifference"><block s="reportListIndex"><l>0</l><block var="n"/></block><l>1</l></block></block><block var="n"/></block></block></block></script><script><block s="doReport"><block s="reportReshape"><custom-block s="crossproduct %mult%l"><block s="reportAtomicMap"><block s="reifyReporter"><autolambda><block s="reportNumbers"><l>1</l><l></l></block></autolambda><list></list></block><block var="n"/></block></custom-block><block s="reportConcatenatedLists"><list><block var="n"/><block s="reportNewList"><list><block s="reportListAttribute"><l><option>length</option></l><block var="n"/></block></list></block></list></block></block></block></script></block></script><script><custom-block s="error %txt"><l>Input to ⍳ can&apos;t be a list of lists.</l></custom-block></script></block></script><script><block s="doReport"><block s="reportIfElse"><custom-block s="zero?

The remaining three inputs are used only if the field values are numbers, in which case they can be grouped into buckets (e.g., decades, centuries, etc.).  Those three inputs specify the smallest and largest values of interest and, most importantly, the width of a bucket (10 for decades, 100 for centuries).  If the field isn&apos;t numeric, leave these three inputs empty or set them to zero.  In that case, each string value of the field is its own bucket, and they appear sorted alphabetically.&#xD;&#xD;The block reports a new table with three columns.  The first column contains the bucket name or smallest number.  The second column contains a nonnegative integer that says how many records in the input table fall into this bucket.  The third column is a subtable containing the actual records from the original table that fall into the bucket.&#xD;&#xD;If your buckets aren&apos;t of constant width, or you want to group by some function of more than one field, load the &quot;Frequency Distribution Analysis&quot; library instead. </comment><header></header><code></code><translations></translations><inputs><input type="%l"></input><input type="%n"></input><input type="%n"></input><input type="%n"></input><input type="%n"></input></inputs><script><block s="doDeclareVariables"><list><l>sorted</l></list></block><block s="doSetVar"><l>sorted</l><custom-block s="sort table %l on field %n in %s order"><custom-block s="group table %l by field %n by intervals of: %n"><block var="data"/><block var="field"/><block var="interval"/></custom-block><l>1</l><l>ascending</l></custom-block></block><block s="doIf"><block s="reportEquals"><block var="interval"/><l>0</l></block><script><block s="doReport"><block var="sorted"/></block></script></block><block s="doReport"><block s="reportMap"><block s="reifyReporter"><autolambda><block s="reportCONS"><block s="reportProduct"><block s="reportListItem"><l>1</l><l/></block><block var="interval"/></block><block s="reportCDR"><l/></block></block></autolambda><list></list></block><custom-block s="bar chart helper function to fill %l key: %repRing from: %n to: %n interval: %repRing with: %repRing"><block var="sorted"/><block s="reifyReporter"><autolambda><block s="reportListItem"><l>1</l><l/></block></autolambda><list></list></block><block s="reportMonadic"><l><option>ceiling</option></l><block s="reportQuotient"><block var="floor"/><block var="interval"/></block></block><block s="reportMonadic"><l><option>ceiling</option></l><block s="reportQuotient"><block var="ceiling"/><block var="interval"/></block></block><block s="reifyReporter"><autolambda><block s="reportSum"><l></l><l>1</l></block></autolambda><list></list></block><block s="reifyReporter"><autolambda><block s="reportNewList"><list><l></l><l>0</l><block s="reportNewList"><list></list></block></list></block></autolambda><list></list></block></custom-block></block></block></script></block-definition><block-definition s="bar chart helper function to fill %&apos;data&apos; key: %&apos;key&apos; from: %&apos;floor&apos; to: %&apos;ceiling&apos; interval: %&apos;interval&apos; with: %&apos;generator&apos;" type="reporter" category="lists"><comment x="0" y="0" w="103" collapsed="false">add missing entries to a sorted list.

The remaining three inputs are used only if the field values are numbers, in which case they can be grouped into buckets (e.g., decades, centuries, etc.).  Those three inputs specify the smallest and largest values of interest and, most importantly, the width of a bucket (10 for decades, 100 for centuries).  If the field isn&apos;t numeric, leave these three inputs empty or set them to zero.  In that case, each string value of the field is its own bucket, and they appear sorted alphabetically.&#xD;&#xD;The block reports a new table with three columns.  The first column contains the bucket name or smallest number.  The second column contains a nonnegative integer that says how many records in the input table fall into this bucket.  The third column is a subtable containing the actual records from the original table that fall into the bucket.&#xD;&#xD;If your buckets aren&apos;t of constant width, or you want to group by some function of more than one field, load the &quot;Frequency Distribution Analysis&quot; library instead. </comment><header></header><code></code><translations>ca:gràfica de la taula _ agrupada pel camp: _ des de: _ fins: _ interval: _&#xD;</translations><inputs><input type="%l"></input><input type="%n"></input><input type="%n"></input><input type="%n"></input><input type="%n"></input></inputs><script><block s="doDeclareVariables"><list><l>sorted</l></list></block><block s="doSetVar"><l>sorted</l><custom-block s="sort table %l on field %n in %s order"><custom-block s="group table %l by field %n by intervals of: %n"><block var="data"/><block var="field"/><block var="interval"/></custom-block><l>1</l><l>ascending</l></custom-block></block><block s="doIf"><block s="reportEquals"><block var="interval"/><l>0</l></block><script><block s="doReport"><block var="sorted"/></block></script></block><block s="doReport"><block s="reportMap"><block s="reifyReporter"><autolambda><block s="reportCONS"><block s="reportProduct"><block s="reportListItem"><l>1</l><l/></block><block var="interval"/></block><block s="reportCDR"><l/></block></block></autolambda><list></list></block><custom-block s="bar chart helper function to fill %l key: %repRing from: %n to: %n interval: %repRing with: %repRing"><block var="sorted"/><block s="reifyReporter"><autolambda><block s="reportListItem"><l>1</l><l/></block></autolambda><list></list></block><block s="reportMonadic"><l><option>ceiling</option></l><block s="reportQuotient"><block var="floor"/><block var="interval"/></block></block><block s="reportMonadic"><l><option>ceiling</option></l><block s="reportQuotient"><block var="ceiling"/><block var="interval"/></block></block><block s="reifyReporter"><autolambda><block s="reportSum"><l></l><l>1</l></block></autolambda><list></list></block><block s="reifyReporter"><autolambda><block s="reportNewList"><list><l></l><l>0</l><block s="reportNewList"><list></list></block></list></block></autolambda><list></list></block></custom-block></block></block></script></block-definition><block-definition s="bar chart helper function to fill %&apos;data&apos; key: %&apos;key&apos; from: %&apos;floor&apos; to: %&apos;ceiling&apos; interval: %&apos;interval&apos; with: %&apos;generator&apos;" type="reporter" category="lists"><comment x="0" y="0" w="103" collapsed="false">add missing entries to a sorted list.

to myself:  When the user sets a fair dimension, say fair HSL, variable HSL contains the corresponding &quot;unfair&quot; values, and &quot;raw HSL&quot; contains the numbers the user actually gave.  It has to be this way because in the case of HSV, there is no &quot;HSV&quot; variable; rather, we use the pen&apos;s actual remembered-by-Javascript color&apos;s HSV coordinates.  So our HSL variable has to be analogous to that.  In both cases &quot;raw&quot; means the numbers the user gave us.</comment><script x="32.333333333333336" y="187.66666666666666"><block s="evaluate"><block

The color can be set in many ways, including RGB values, HSV values, HSL values, fair HSV or HSL (based on a modified spectrum that gives each spectral color equal space and promotes brown to a color), color number, crayon, or X11/W3C color name.&#xD;&#xD;See Appendix A in the Snap!

It has to be this way because in the case of HSV, there is no &quot;HSV&quot; variable; rather, we use the pen&apos;s actual remembered-by-Javascript color&apos;s HSV coordinates.  So our HSL variable has to be analogous to that.  In both cases &quot;raw&quot; means the numbers the user gave us.</comment></scripts></block-definition><block-definition s="mmap %&apos;function&apos; over %&apos;lists&apos;" type="reporter"

+/* Signada - a network remote control procotol
+ * ===========================================
+ * By Bernat Romagosa, August 2021
+ *
+ * Enables Snap! to talk to wifi-enabled
+ * MicroBlocks devices.
+ *
+ * This protocol was designed for the Citilab
+ * ED1 microcontroller board, but it can be
+ * used for any ESP32 board that has a display
+ * and two buttons, like the M5Stack.
+ *
+ * First, load the Signada example project
+ * from the MicroBlocks IDE and follow the
+ * instructions on the long comment in that
+ * project.
+ *
+ * Get MicroBlocks at https://microblocks.fun

     documentation
     -------------
-    the experimental Snap! API is a set of methods for an IDE_Morph containing
-    a Snap! project. These methods are maintained to work with future versions
-    of Snap! They can be used to trigger scripts, get feedback from running
-    scripts, and access the project's global variables. Currently the API
-    consists of the following methods:
-
-        Broadcast Messages (and optionally wait)
-        
-            - IDE_Morph.prototype.broadcast()
-
-        Listen to Messages
-
-            - IDE_Morph.prototype.addMessageListenerForAll()
-            - IDE_Morph.prototype.addMessageListener()
-            - IDE_Morph.prototype.getMessages()
-
-        Access Global Variables
-
-            - IDE_Morph.prototype.getVarNames()
-            - IDE_Morph.prototype.getVar()
-            - IDE_Morph.prototype.setVar()
-
-        Create and Modify Lists
-
-            - IDE_Morph.prototype.newList()
-
-        Access the Serialized Project
-
-            - IDE_Morph.prototype.getProjectXML()
-            - IDE_Morph.prototype.loadProjectXML(projectXML)
-            - IDE_Morph.prototype.unsavedChanges()
-
-    Getting hold of an ide can usually be achieved by
-    evaluating:
-
-        var ide = world.children[0];
-
-
-    IDE_Morph.prototype.broadcast()
-    ===============================
-    The broadcast() method triggers all scripts whose hat block listens to
-    the specified message. An optional callback can be added to be run
-    after all triggered scripts have terminated.
-
-        syntax:
-        -------
-            ide.broadcast(message [, callback]);
-
-        parameters:
-        -----------
-            message
-                string, the message to be sent to all listeners
-            callback | optional
-                function to execute after all scripts terminate, no arguments
-
-        return value:
-        -------------
-            undefined
-
-
-    IDE_Morph.prototype.addMessageListenerForAll()
-    ==============================================
-    The addMessageListenerForAll() method sets up a function that will be
-    called whenever a message is broadcast. The function takes one argument,
-    the message being broadcast, and can be used to react to any message.
-    Multiple message listeners can be set up, they all the executed in the
-    order in which they were added.
-
-        syntax:
-        -------
-            ide.addMessageListenerForAll(callback);
-
-        parameters:
-        -----------
-            callback
-                function to execute whenever a message is sent,
-                takes one argument: The message string
-
-        return value:
-        -------------
-            undefined
-
-
-    IDE_Morph.prototype.addMessageListener()
-    ========================================
-    The addMessageListener() method sets up a function that will be called
-    whenever the specified message is broadcast. Multiple message listeners
-    can be set up per message, they all get executed in the order in which
-    they were added.
-
-        syntax:
-        -------
-            ide.addMessageListener(message, callback);
-
-        parameters:
-        -----------
-            message
-                string, the message to which the listener will react.
-                If the message is an empty string the callback will
-                be executed at any broadcast, passing the message as
-                argument
-            callback
-                function to execute whenever the specified message is sent,
-                takes no argument, except when the message to listen to is
-                the empty string, then it takes the message as argument
-
-        return value:
-        -------------
-            undefined
-
-
-    IDE_Morph.prototype.getMessages()
-    =================================
-    The getMessage() method returns a new Array that contains all the message
-    strings that occur in the project, both in hat blocks and in broadcast
-    blocks.
-
-        syntax:
-        -------
-            ide.getMessages();
-
-        return value:
-        -------------
-            an Array of strings, or an empty Array
-
-
-    IDE_Morph.prototype.getVarNames()
-    =================================
-    The getVarNames() method returns a new Array that contains all the global
-    variable names in the project.
-
-        syntax:
-        -------
-            ide.getVarNames();
-
-        return value:
-        -------------
-            an Array of strings, or an empty Array
-
-
-    IDE_Morph.prototype.getVar()
-    =============================
-    The getVar() method returns the value of the global variable indicated by
-    the specified name.
-
-        syntax:
-        -------
-            ide.getVar(name);
-
-        return value:
-        -------------
-            whatever value the variable holds.
-
-
-    IDE_Morph.prototype.setVar()
-    ============================
-    The setVar() methods assigns a value to the a global variable specified
-    by name.
-
-        syntax:
-        =======
-            ide.setVar(name, value);
-
-        return value:
-        =============

+    SnapExtensions is a set of two global dictionaries of named functions to be
+    used as extension primitives for blocks or dynamic dropdown menus. Block
+    extensions are stored in the "primitives" dictionary of SnapExtensions,
+    dynamic dropdown menus in the "menus" section.
+    
+    You can also extend Snap! with your own externally hosted JavaScript file(s)
+    and have them add your own extension primitives and menus to the global
+    SnapExtensions dictionaries. This lets you provide libraries to support
+    special APIs and custom hardware.
+
+    
+    1. Primitives (additional blocks)
+    =================================
+    The names under which primitives are stored will apear in the dropdown
+    menus of the hidden extension "primitive" blocks sorted alphabetically.
+    (You can find those extension primitives in Snap's search bar or in dev
+    mode. There are two version of the primitive block, a command version and
+    a reporter one, both show the same list of available extensions.
+
+    naming conventions
+    ------------------
+    domain-prefix_function-name(parameter-list)
+    example: 'lst_sort(list, fn)'
+
+    - domain-prefix:    max 3-letter lowercase identifier
+                        followed by an underscore
+               e.g.:    err_, lst_, txt_, dta_, map_, tts_, xhr_, geo_, mda_
+
+    - function-name: short, single word if possible, lowercase
+    - parameter-list: comma separated names or type indicators
+
+    function semantics
+    ------------------
+    - functions are called by the "primitive" blocks with any arguments provided
+    - use the "function () {}" notation to define functions, not the ES6 arrow
+      notation, otherwise "this" will not get scoped correctly
+    - "this" refers to the current snap object (sprite or stage) at call-time
+    - a reference to the current process is always passed as last argument
+
+
+    2. Menus (for input slots)
+    ==========================
+    The names of the available dynamic drowdown menus can be written into the
+    "options" dialog when defining an input slot. Additionally you can choose
+    from a list of available menus when holding down the shift-key while
+    clicking on the partial-gear button in Snap's input-slot dialog.
+
+    naming conventions
+    ------------------
+    domain-prefix_function-name
+    example: 'clr_number'
+
+    - domain-prefix:    max 3-letter lowercase identifier
+                        followed by an underscore
+               e.g.:    clr_, txt_, lst_
+
+    - function-name: short, single word if possible, lowercase
+    - NOTE: dynamic menu functions cannot have any inputs
+
+    function semantics
+    ------------------
+    - use the "function () {}" notation to define functions, not the ES6 arrow
+      notation, otherwise "this" will not get scoped correctly
+    - "this" refers to the current input-slot at call-time (when the menu is
+      requested by the user by clicking on the down-arrow symbol)
+    - to get a handle on the current block use "this.parentThatIsA(BlockMorph)"
+    - likewise to get a handle on the current sprite use
+      "this.parentThatIsA(IDE_Morph).currentSprite"
+    - if you want the menu of one input slot to depend on the contents of
+      another input slot of the same block, you can get a handle to the block
+      using the above method, and then access all inputs by calling
+      "block.inputs()". This will give you an array of all input slots.
+      You can access the contents of an input slot by calling "slot.evaluate()"
+
+
+    3. External JavaScript files
+    ============================
+    You can provide extensions for your custom hardware or for arbitrary APIs
+    or extend Snap! with JavaScript libraries from other parties. You can
+    load additional JavaScript files using the
+    
+        src_load(url)
+    
+    extension primitive inside Snap, which you can find using Snap's search bar
+    in the IDE. The loading primitive will wait until the source file has fully
+    loaded and its defined functions are ready to be called.
+    Snap remembers the external extensions that have been already loaded and
+    will ignore any subsequent calls to load the same external extension again.
+    This lets you lazily initialize your extension by simply adding a
+    "src_load(url)" command for your external JS file before calling any of its
+    added functions.
+    
+
+    4. Miscellaneous
+    ================
+
+    calling extension primitives in other JavaScript functions
+    ----------------------------------------------------------
+    you can call other extension primitives from your own JavaScript functions,
+    especially if you want to reuse them in your own extensions. Just make sure
+    to use apply() instead of calling them directly, so "this" gets scoped
+    correctly, e.g.:
+
+        SnapExtensions.primitives.get('var_declare(scope, name)').apply(
+            this,
+            ['global', '_my var', proc]
+        );
+
+    Don't forget to pass in a reference to the current process as last parameter
+    in case the callee requires it.
+
+    adding primitives to SnapExtensions
+    -----------------------------------
+    It is the suggested best practice to expose your own extension primitives
+    by adding them to the global SnapExtensions libraries (for primitives and
+    menus) using the very same conventions described herein, and then to offer
+    a library of custom blocks that make calls to your additional operations.
+
+    developing an extension
+    -----------------------
+    Running the "src_load(url)" primitive will throw an error unless you first
+    check the "Enable JavaScript extensions" setting in Snap's preferences menu,
+    or if your JavaScript extension comes from a list of trusted hosts.
+    While you develop your JavaScript extension it's recommended to turn on the
+    "Enable JavaScript extensions" setting to load the extension once, and
+    then to turn it off again, so you can make sure your custom blocks are not
+    using any "JS Function" blocks (because those will be caught if the
+    preference is turned off).
+
+    publishing an extension
+    -----------------------
+
+    When you're ready to publish your extension you can contact us to allow-list
+    the url hosting your JS file, or you can send me a Github pull-request to
+    include it in the main Snap branch.
+    We recommend submitting your extensions to the main Snap! Github repository
+    so they can be made available in the offline versions (source download
+    and PWA).
+    External extensions are a powerful tools to change, override and generally
+    mold Snap into anything you want, so please use these capabilities sensibly.
+    We look forward to your innovations and don't plan to restrict the scope of
+    what extensions are allowed to modify. For security reasons we do ask you to
+    refrain from exposing any form of JS eval(), including "new Function()" to
+    end users (if you want to use eval() internally in your extension we'll
+    frown on you but not reject your contribution).

+    scenes have been inspired by Ted Kaehlers's personal demos of HyperCard

+    and by personal discussions with Wolfgang Slany about his design of
+    scenes in Catrobat/PocketCode, which I love and admire.
