Several people on this board have been asking for the shortcuts.

Coalado, jD developer, referred to the language file for the shortcuts. After some searching I found some of them (the keys start with "gui.menu.action") in my English language file. I'm not sure whether my list is complete.

Since they are defined in the language files, they might be language dependent. Please, check your own language file if you're using another langauge.

Shortcuts :-
Edit by Jiaz: please note that shortcuts can differ between the different languages, check languagefile for more info
