I'm currently using CheatSheet.app on OS X (10.9 if that matters). This app displays the shortcuts of the application in focus with a shortcut.
Sadly, for some programs, IDEs for instance, only a fraction of them are displayed. I'd like to be able to design my own cheat sheet for some programs.
Do any of you know of an alternative to this software that would offer this kind of functionalities? An open-source alternative would be fine too. I may try to implement the functionality myself.
