I've been using keyboard shortcuts since they were included in the ***Accelerators section of the old Menu files and still have to check an online link to remember ones I don't use very often once in a while. Changing any of them would make keeping track of what they're set to a nightmare.
The only keyboard shortcut I've ever added was to toggle the Tilemode system variable On/Off to switch between the Model tab and the previous Layout tab and since there was no keyboard shortcut for Ctrl+T it's easy to remember it's for Tilemode.
The shortcut Key macro is:
^C^C^P(ai_onoff "tilemode") Regen ^P
Edit: Just remembered I do change the Shortcut Key CTRL+H from
'_setvar;pickstyle;$M=$(if,$(eq,$(getvar,pickstyle),0),1,$(if,$(eq,$(getvar,pickstyle),1),0,$(if,$(eq,$(getvar,pickstyle),2),3,2)))
to ^A
Which was the Original Shortcut for toggling Group selection that's still built in to AutoCAD.
That way when I use it it displays <Group Off> or <Group On> at the Command Line so I know what I just did.
