So I was correct with the global-grab and non-kde theories! =:^)
But I was somewhat thrown off by the assumption that someone would have
tested that keystroke in other apps, before posting a question about it
that blamed the problem on konsole. Still, while specific window global-
level-grabs (perhaps specific-window X-level is a better description
here, since the grabs aren't really global, tho the would be if not
limited to a specific window) are indeed possible, since they're less
common, I was forced to assume that either that testing had NOT taken
place, or a rather less common grab mode was being used, and my proposed
tests reflected the fact that I wasn't sure of that assumption. So it
threw me off only slightly, and the test results would have confirmed the
fallacy of that assumption, bringing us right back on course toward a
trace-down.
As for "hijacking" Ctrl-f, while modern x86 keyboards generally have a
meta/super/hyper/windows/linux key that due to its relatively recent
invention, doesn't show up on so many app-level key-bindings, so it's a
relatively safe key to use for global bindings, apps that don't assume it
exists (or is configured correctly), as xbindkeys apparently doesn't,
don't have the luxury of using that key for global bindings and thus
avoiding the standard, often already bound, control/alt/shift modifier
combos.
As a result there's bound to be conflicts when such bindings are global-
grabbed, and the author was forced to either ship with few if any global-
grabs active by default, or to assume that a user advanced enough to go
looking for and installing a global-grab hotkey app, would also be
advanced enough to look over the default grabs and deactivate or modify
the ones that didn't suit his purposes.
It seems both his assumption, that anyone advanced enough to go looking
for and install such an app would immediately check the config and modify
it to their own purposes, and mine, that anyone trying to trace strange
key behavior would test it in more than one app before posting, blaming
it on a single app, were both incorrect.
Oh, well...
At least the problem was traced and corrected, tho. That's the important
bit! =:^)
