How to add hotkey?

[Chlorek]

Hi there. I am new to Minecraft Modding (I know bascis of Forge), but I am experienced with Java and BukkitAPI. However this time I am writing some mod without any other "core" mod. Pure Vanilla functions etc.

So, I don't know how to add simple hotkeys to toggle functions in my mod. Probably answer is really simple, but I have no time to search in source code. I tried 'googling' but I haven't found anything.

Thanks for help, Chlorek.
