example: you can type 'CC' instead of 'CO' for the 'COPY' command or 'TE' instead of 'DDEDIT' for the dynamic text editor command, to save valuable tenths of seconds.
ive done this procedure in AutoCAD R14, 2000 and 2002. im sure 2004+ is the same.
go into your AutoCAD support directory (default filepath is C:\Program Files\AutoCAD 2000\Support\...)
find the ACAD.PGP file and open it in notepad or another text editor.
make sure you have a backup pgp file, then
scroll down and find the command that you want to change the shortcut for, on the left, type:
XX,(tab and a few spaces)*XXXXXXX
where 'XX' is the new shortcut, and XXXXXXX is the default command.
use common sense to match the format of the rest of the shortcuts, and make sure what you entered lines up with the rest. for example, to add the 'CC' shortcut for the 'copy' command, scroll down until you find:
then add a new line under it and type ' CC, (tab) *copy ' so you see this:
CO, *copy CC, *copy
in the above example, both the default 'CO' as well as the new 'CC' shortcuts both open the 'COPY' dialog.
