[Framers] FrameMaker keyboard shortcuts just stop

[Ken Poshedly]

Folks,
At least every other day, and for no reason obvious to me, all keyboard shortcuts in FrameMaker will stop working after awhile and all tasks must be done via menus-and-mouse. For me, this such a PITA. And it happened again this morning. This has been going on forever. (Well, you know what I mean.)

The only fix I know of is to close everything, exit FM, re-open FM and so forth.

Is there, praytell, an undocumented feature that toggles keyboard commands on and off?
I await ye answers.

Duck!)(Thanks to wonders of fast-curing concrete, a 24/7 work schedule and really nice weather, the latest re-opening date was moved back from September to mid-June to May 26. Lots of well-deserved bonuses.)Oh, and the five pro-bono lawyers for the crackhead who started the fire is blaming the state DOT. We can discuss this off-list.
