letins Default shortcuts for let say "Step forward 1 frame" and "Step forward many frames" are "Right" and "Shift Righ", but if I try to implement them into my User commands, they don't work.
Is Numlock enabled when you execute those commands?
letins Shortcuts have multiple uses for different selected panels and whatnot
that blue text next to shortcut is just a cue for a user for what he wants to do. There is no way for me to define which panel is active, so you can just select proper name for your keyboard shortcut press (e.g. during User Command you switch to Project panel and perform there some specific shortcut and you want it to have name that related to Project panel, not Timeline panel).
