thank you, but according to your advice , the only command I can assign a shortcut is "show archiruler palette" which is not useful for drawing accelerating.
if there any shortcut for drawing a line or other command in arhciruler?
Sorry, I do not actually have ArchiRuler on my system but if that is the only command available then I doubt there is any other way to invoke other commands, short of contacting Fabrizio and begging for it.
