The IDLWAVE shell works in the same fashion as other shell modes in Emacs. It provides command history, command line editing and job control. The <UP> and <DOWN> arrows cycle through the input history just like in an X terminal1. The history is preserved between emacs and IDL sessions. Here is a list of commonly used commands:
|<UP>, M-p||Cycle backwards in input history
|<DOWN>, M-n||Cycle forwards in input history
|M-r||Previous input matching a regexp
|M-s||Next input matching a regexp
|return||Send input or copy line to current prompt
|C-c C-a||Beginning of line; skip prompt
|C-c C-u||Kill input to beginning of line
|C-c C-w||Kill word before cursor
|C-c C-c||Send ^C
|C-c C-z||Send ^Z
|C-c C-\||Send ^\
|C-c C-o||Delete last batch of process output
|C-c C-r||Show last batch of process output
|C-c C-l||List input history
In addition to these standard comint commands,
idlwave-shell-mode provides many of the same commands which
simplify writing IDL code available in IDLWAVE buffers. This includes
abbreviations, online help, and completion. See Routine Info and
Online Help and Completion for more information on these
|<TAB>||Completion of file names (between quotes and after executive
commands ‘.run’ and ‘.compile’), routine names, class names,
keywords, system variables, system variable tags etc.
|M-<TAB>||Same as <TAB>
|C-c ?||Routine Info display (|
|M-?||IDL online help on routine (|
|C-c C-i||Update routine info from buffers and shell
|C-c C-v||Find the source file of a routine (|
|C-c C-t||Find the source file of a routine in the currently visited file
|C-c =||Compile a library routine (|
nilmeans <UP> and <DOWN> arrows move through command history like xterm.

The characters allowed in file names, as a string. Used for file name completion.

IDLWAVE works in line input mode: You compose a full command line, using
all the power Emacs gives you to do this. When you press <RET>, the
whole line is sent to IDL. Sometimes it is necessary to send single
characters (without a newline), for example when an IDL program is
waiting for single character input with the
You can send a single character to IDL with the command C-c C-x
idlwave-shell-send-char). When you press C-c C-y
idlwave-shell-char-mode-loop), IDLWAVE runs a blocking loop
which accepts characters and immediately sends them to IDL. The loop
can be exited with C-g. It terminates also automatically when the
current IDL command is finished. Check the documentation of the two
variables described below for a way to make IDL programs trigger
automatic switches of the input mode.
nilmeans IDLWAVE should check for input mode spells in output.

 This is different from
normal Emacs/Comint behavior, but more like an xterm. If you prefer the
default comint functionality, check the variable
