Ctrl, Shift & Alt (Over multiple forms)

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Question:
Can anyone tell me how to >>reliably<< monitor Command Key states
inside my application to alter the interface?

Situation: (Skip to Problem if it gets tedious)
Application consisting of multiple forms, uses Ctrl, Shift & Alt to
alter the behavior of command buttons. In addition to altering the
behavior of command buttons, holding down a command key alters the
interface, showing captions describing the altered behaviors.

Example (ShiftState / Behavior)

0 / Save
1 / Save (only) Selected items
2 / Save (only) Filtered items
3 / Save Selected Filtered items
....

Command buttons check Shift states and with KeyDown/KeyUp on the forms,
Shift is routed to a central sub which controls Command button
captions. It works, but poorly.

Problem:
When holding-down (combinations of) Ctrl, Shift and Alt is used to
browse the interface, at times it gets stuck. Sometimes it seem all of
the forms have lost focus somehow (and you have to click a form and
jiggle the keys to reset) or a keycombo is stuck (in KeyDown?) (and you
have to jiggle the keys to reset.)
