As I don't believe this is a feature already... at least not one that I know how to access.
We currently have hotkeys, yes. but only one through ten.
My thought is to be able to make more then one hotkey set and to be able to cycle through them.
This way I and others could let's say designate a hunting/pvp set of hotkeys, and on another set let's say have it be crafting related or silkmoth farming related. etc.
They could be then accessed by perhaps holding alt or another key and pressing a number to access the new hotkey set while saving the old one.
