The transmit buffer for fldigi is type ahead which means that you
|
|
can be typing text while the program is sending an earlier part of your
|
|
transmitted message.
|
|
|
|
Newly entered text appears in black and text which has been transmitted
|
|
is changed to red. You can backspace into the red area. When you do and
|
|
the modem in use supports the BS character it will be sent to the receiving
|
|
station. If you monitor PSK and MFSK signals you will often find operators
|
|
backspacing over previously sent text. It's probably just as easy to just
|
|
send XXX and retype that part of the message, but we have gotten used to
|
|
word processors, email, etc. that allow us to send perfect (right) text, so
|
|
we expect our digital modems to do the same. Let's see, what was that
|
|
prosign often used in CW for oooops.
|
|
<br>
|
|
|
|
All of the alpha numeric keys perform as you would expect, entering
|
|
text into the transmit buffer. There is one very important
|
|
exception:
|
|
<br>
|
|
|
|
The caret "^" symbol. This is used in the macro expansion routine
|
|
and also used by the transmit buffer evaluator. A ^r puts fldigi into
|
|
receive mode. So you can enter the ^r (caret followed by the r) at the end
|
|
of your transmit buffer and when the sent character cursor (red chars) gets to
|
|
that point the program will clear the text and return to the receive
|
|
mode.
|
|
<br>
|
|
|
|
You can load the transmit buffer with any ASCII Text file of your
|
|
choice. Merely right click in the buffer window and select from
|
|
the pop-up menu. You can also short cut to the ^r from
|
|
this popup.
|
|
<br>
|
|
|
|
Many ops (including me) do not like to be tied to a mouse. The
|
|
fldigi text widget supports some short cuts to make your life easier:
|
|
<br>
|
|
|
|
<ul>
|
|
<li>Pause/Break - a transmit / receive - pause button. </li>
|
|
<ul>
|
|
<li>if you are in the receive mode and press the Pause/Break key the
|
|
program will switch to the transmit mode. It will begin transmitting
|
|
characters at the next point in the transmit buffer following the red
|
|
(previously sent text). If the buffer only contains unsent text,
|
|
then it will begin at the first character in the buffer. If the
|
|
buffer is empty, the program will switch to transmit mode and
|
|
depending on the mode of operation will send idle characters or
|
|
nothing at all until characters are entered into the buffer.</li>
|
|
|
|
<li>if you are in the transmit mode and press the Pause/Break key
|
|
the program will switch to the receive mode. There may be a slight
|
|
delay for some modes like MFSK, PSK and others that require you to
|
|
send a postamble at the end of a transmission. The transmit text
|
|
buffer stays intact, ready for the Pause/Break key to return you to
|
|
the transmit mode.</li>
|
|
|
|
<li>Think of the Pause/Break key as a software break-in capability.</li>
|
|
</ul>
|
|
|
|
<li>Esc - </li>
|
|
<ul>
|
|
<li>Abort transmission. - immediately returns the program to receive,
|
|
sending the required postamble for those modes requiring it. The
|
|
transmit buffer is cleared of all text.</li>
|
|
|
|
<li>Triple press on Esc - terminates the current transmission without
|
|
sending a postamble - The PANIC button.</li>
|
|
</ul>
|
|
|
|
<li>Ctrl-R will append the ^r (return to receive) at the end of the
|
|
current text buffer.</li>
|
|
|
|
<li>Ctrl-T will start transmitting if there is text in the transmit
|
|
text window.</li>
|
|
|
|
<li>Alt/Meta-R will perform the same function as the Pause/Break key</li>
|
|
|
|
<li>Tab moves the cursor to the end of the transmitted text (which
|
|
also pauses tx). A tab press at that position moves the cursor to the
|
|
character following the last one transmitted. CW operation is slightly
|
|
different, see the help for \ref cw_page .</li>
|
|
|
|
<li>Ctrl + three digits will insert the ASCII character designated by
|
|
that entry.</li>
|
|
|
|
</ul>

\section function_keys Function Keys
|
|
|
|
Keys F1 through F12 are used to invoke the macro F1 - F12. You
|
|
can also just click on the macro key button associated with that
|
|
function key. There are 4 sets of 12 macros. If you press the numbered
|
|
button on the macro button bar the next set of macros are referenced by
|
|
the F1 - F12. A right click on the numbered button provides a reverse
|
|
rotation through the 4 sets of macro keys. The respective macro set can be
|
|
made available by pressing the Alt-1, Alt-2, Alt-3 or Alt-4 key
|
|
combination. Note that this is not Alt-F1 etc.
