By the way, Speedbar can be turned on by default, or with
Tools->Display Speedbar in the Emacs menu. Middle click on things (or
use arrows and return). I also use "iMenu" bound to
Shift-Right-Click, to popup a list of routines in my file (see the
IDLWAVE screenshots at idlwave.org).

That's a great idea. You might also see the troubleshooting FAQ:

Nope... I don't even know what's in the those files. You can have lots of
fun with "speedbar", which is an Emacs way to browse files, and the
contents of files (like routines) in a sidebar. I've never use the
project feature; I tend to organize by directory.

I hadn't actually seen this... if you have (X)Emacs >=21, you can get a
recent files list in the File menu using the "recentf" package, like this
(in your .emacs):
(require 'recentf)
(recentf-mode 1)
The list is automatically saved between Emacs sessions.

The way to "visit" routines in IDL is with C-c C-v. This works with
fragments of routines, and gives you a completion prompt to pick a
routine. If you just want to quickly visit the source code of a routine,
you can use the Help feature for that (C-c ?), and it will popup in a
read-only help frame, which can be dismissed with "q".
That reminds me to make these work inside of executive commands in the
shell too. That said, you really should not be typing ".compile
myprogram". You should visit myprogram in a buffer, and C-c C-d C-c
it (or hit the "Save and Compile" button), and watch any compilation
errors get highlighted, etc.

Other than "emacs *.pro" ;)? I bet it would be easy to use the list
that recentf provides, and open all of those files which match *.pro.
IDLWAVE leaves all notions of "project" to your organization. I
personally just organize by directory.

Push the button that is called "Save and Compile". Or, if you have a
complicated expression you keep running over and over, like:
my_long_routine,1,2,3,KEYWORD1=12.
You can save it as the "default command line" with C-c C-d C-y (or the
button at the top that looks like a text entry underscore), and run
with the same, so your not limited to just "running" main level
routines, but instead can repeatedly execute complex expressions.

Keep them coming. It's always good to get the new user's perspective.
