Shortcut for "enable keyboard"?

Could we please have a keyboard shortcut for toggling “enable keyboard” (that shortcut would obviously not send to the VSTi then, when keyboard is enabled).

I am asking, because for some plugins (e.g. U-he Zebra2) most mouse actions also only work when “enable keyboard” is selected (not really sure why, but that is the case), and having to move the mouse constantly to to that tickbox when switching from tweaking the synth to quickly testing the effects of that tweak (by playing a note withe the keyboard), is very very annoying.

Alternatively, a fix for synths that need “enable keyboard” for mouse interactions would also be very welcome.
