Amazon sells specialized programmable keyboards for this for like $200
Or for $60 you can take a sharpie to a blank key with one of these bad boys
Best to just use the tools you have though. A regular keyboard is perfect, you just need to change the settings to suit your needs.
Mnemonics help. VG for visual graphics. AL for align.
But AL is too far away on the keyboard for one handed operation. Switch it to AS for align shit. Switch move to MSPACEBAR and copy to CSPACEBAR.
DI for dimension is fine, but for frequent commands double letters are better. DD for dimension, LL for load family, BB for section box, CS for create similar, SS for split element, etc.
