I was under the impression any wps context menu item could be added as a hotkey?
Every hotkey action needs to be added manually (before compile time) at present.
IIRC Blue Dude *did* want to be able to add items to the hotkey in exactly the same fashion as quickscreen...but if you'll remember the development of hotkey turned out to be a lot more than Blue Dude intended it to be in the end and I think he was happy just to get it in a committable state.
For now, there's a pre-defined list of hotkey options.
Last added to that was me convincing him to add "Insert Shuffled" to it.
But yeah, ...I'd welcome being able to define hotkey options for the Filebrowser/WPS(/Database too?) from the context menu...that would be awesome.
