It would be handy to have a personal list, where you can add your favorite and most used keyboard shortcuts.You can open this list, looking at it permanently to remember/having an overview or to modify it. Also clicking on one shortcut/macro on the list it is working. The list should be devidable with different headlines and with seperated macros for a better overview. This list should show the command, the assigned key(s) and the kategory if it has one.
Beside that there could be a picture of a keyboard where all the used keys of you personal shortcuts on your own list are green on it and all the not used white.
