Possible enhancement request

[Mike Kerner]

for good or bad, the lcb style guide section on events as excerpted, here
<https://github.com/macMikey/LCB-missing-manual/wiki/LiveCode-Builder-Style-Guide#events>
says
that those events are recommended, but not required.
in many of those widgets, it would also be nice if there was a way to
intercept the click, and decide what to do, before it is just done.
that's part of what led to the birth of the "navrad" widget - intercept a
click in the navbar and decide whether the hilite should be allowed to
change or not, instead of changing the hilite first, and then undoing it if
it should not have been allowed.

On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
