Reassigning Hotkeys?

Hey is it possible to swap out hotkeys? Or at least assign some to actions that don’t have them? I mainly just want to have some hotkeys for rotate CW and CCW like TBS had – in H Ess. there’s no default key for them. There a way I can assign some defaultly empty keys to them?

Thanks guys.

Cmd + Alt + Mouse Drag. This is by default and works fine.
If you don’t like it - just go to Preferences. 1st tab is for the shortcuts, type there “rotate” in Search field and use the arrows to see what’s default, options etc before you’ll change sth.
