Right, apparently apps have this problem when running under Vista and up
because the window manager is intercepting the sequence before the apps
can get them.
Cross platform application programmers have to navigate a veritable
mine field
of keyboard shortcuts the evolving window managers throw at us.
I'm not sure there's a good central document that itemizes them all,
but there are platform specific lists from the various vendors.
I ran into these while researching the 'standard' text editor keys
which we recently redefined to tear FLTK away from its SGI roots.
I accumulated all the info I could find, resulting in this
"Fl_Input platform-specific keyboard bindings" table:
http://fltk.org/doc-1.3/classFl__Input.html
I may have posted links to the reference docs on fltk.dev; if I can find
them, I'll follow up here.
As I recall, windows, OSX and free desktop/linux each had pages listing
all
the window manager shortcuts, as well as commonly used sequences for
apps
(Ctrl-C, Ctrl-V, etc..) These were of course different from one release
to the next.
The users of apps that have lots of shortcuts (like GIMP) have to
reprogram
their muscle memory whenever their favorite shortcuts are eclipsed by
some new window manager function that app programmers can't anticipate.
