I'm not sure where you're having trouble, so here some semi-random tips:

1. Emacs on Windows http://ourcomments.org/Emacs/EmacsW32.html

2. You can turn on some Emacs keybindings in DrRacket / DrScheme by
choosing Preferences > Editing > General and unchecking "Enable
keybindings in menus".

3. "c:a" means control-a. Other examples, culled from the source code, include:

"f5" "c:tab" "c:s:tab" "d:s:right" "c:x;0"

c:s:tab => control+shift+tab
I don't what d stands for, but presumably it is "alt"
"c:x;0" means control+x then 0

Hopefully you can work out what the others mean.

I doubt you can easily do that.
