i propose to add a "Key Focus" event for each control. We already have Mouse events (leaving, entering) - but when the user (or the programmer) prefers the keyboard (with proper tabbing setup) you have to poll each interesting control for it's "Key Focus" property to initiate a user event...
Add a "Got Focus" (and additionally a "Lost Focus") event to the event structure!
