Fldigi has a bewildering number of keyboard and mouse shortcuts, some
of which may help make your particular style of operation more
efficient.  You do not need to know them all to make effective use
of the program!
<br>

\section main_window Main window
<br>

\subsection text_input_fields Text input fields
<br>

Most text fields use a combination of CUA (PC) and Unix-style
keybindings.  Text can be marked, copied, pasted, saved to a file
as well as transfer to other main panel controls.  A right click
on any text control will open a context sensitive menu for that
particular control.  A full list can be found on the
<a href="http://www.fltk.org/doc-1.1/Fl_Input.html">FLTK web site</a>
<br>

The received/transmitted text widgets use CUA key bindings with some
modifications:

\subsubsection rx_text RX text

This widget is read-only and ignores shortcuts that would modify its contents.
See \ref qso_log_book_page "logbook" for details on the Rx right click
popup menu system.
<br>

\subsubsection tx_text TX text

The text that has already been sent is protected, but can be deleted one
character at a time with the Backspace key.  Right clicking on the Tx text
panel opens the following popup menu:
<br>

<br>

<br>

<ul>
	<li>Transmit<br> put the program into the transmit operation</li><br>
	<li>Receive<br>during a transmit or tune, end the transmit and restore
	receive operation</li><br>
	<li>Abort<br>during a transmit, receive without waiting for the modem to
	finish sending</li><br>
	<li>Send image<br>for MFSK only, send an image using MFSKpic mode</li><br>
	<li>Clear<br>clear all of the text</li><br>
	<li>Cut<br>delete the marked text (by left click drag over text)</li><br>
	<li>Copy<br>copy the marked text to the clipboard</li><br>
	<li>Paste<br>the clipboard text to the current text insertion point</li><br>
	<li>Insert file<br>select a file from file browser to insert in text at
	insertion point</li><br>
	<li>Word wrap<br>turn word wrap on/off</li><br>
</ul>

The Tx panel is fully drag and drop aware.  That means you can add a
file to the transmit text by simply opening up a file manager
(different for different OS and choice of desktop).  Select the
file from the manager and then drag and drop it onto the Tx panel. The mouse
pointer will move the cursor insert point for the drop.
<br>

A number of additional shortcuts can be found in the
\ref keyboard_operation_page "Keyboard Operation" section.

Most of fldigi's unusual shortcuts are specific to this widget.

	select the next channel</li>
	<li>Shift-Left click/drag  same as unmodified left click; no signal
	search</li>

	frequency when the button is released, no signal search</li>
	<li>Shift-mouse wheel - move the squelch slider</li>

    such as the FT-950, will set the transceiver manual notch frequency to
    the frequency under the mouse cursor.  Repeat the Ctrl-Alt-Left click
