Hotkey grouping

[javiermarinros]

It would be nice to group hotkeys by section or functionality, something like this:

[Antariano]

+1

[dan-silver]

+1

[silverprize]

+1
or I hope hotkey service provide to swap keyset.

[kfei]

+1

Sorry for the delay here, I'm trying to clean up old tickets. If this is important to you guys, please open a PR for it. Thanks!

Hey @chieffancypants, any chance you could merge #205 any time soon? Thanks for this great module!
