This is a report on behalf of SebHoll who has trouble signing up.

Shortcut keys which use the Ctrl key (left or right) stop responding when Caps Lock is on. This doesn't happen with Alt, Sys or Shift keys for some reason. It only happens on Linux (probably due to its case-sensitive nature), it has been tested in Windows and ubuntu.
For a quick example run test/editor and try the menu shortcuts.

* Bump *

Anyone else able to verify this behaviour?

Yes, I can confirm this. My quick testing seems to indicate that NumLock do not have an effect. The shortcut doesn't work only when CapsLock is on.

Is this what you are seeing too?

My system:
openSUSE 11.2
KDE 4.2.4
FLTK 1.3.0-r6841

Yep, pretty much.  But also, I have a shortcut that is Ctrl+Shift+F, and this doesn't work with Caps-Lock off, so that implies it is definitely something to do with case...

Using the attached foo.cxx program which sets the shortcuts with:

    menu->add("Testing/Ctrl-Shift-F", "+^f", Callback);
    menu->add("Testing/Ctrl-F",       "^f",  Callback);
        
..I can confirm the following behavior on Ubuntu7 + FLTK1.3.x current:

    o Ctrl-Shift-F -- shortcut only works when capslock ON, not OFF
    o Ctrl-F       -- shortcut only works when capslock OFF, not ON

..in other words, completely opposite behaviors.

Note: if I make the 'f' in the shortcut setup to uppercase, eg:

    menu->add("Testing/Ctrl-Shift-F", "+^F", Callback);
    menu->add("Testing/Ctrl-F",       "^F",  Callback);

..when the CTRL_SHIFT-F works OK regardless of the state of capslock,
and Ctrl-F does NOT WORK AT ALL, regardless of the state of capslock.

I'd think the case of the 'F' used in setup shouldn't matter; the only thing that should affect case is if the Shift flag were specified or not.

Does anyone have Ubuntu installed and can try to fix this?

Please see the current activity in STR#2366 for a possible
one line fix for this (acr's reply and the "acr-fix.patch").

I can confirm the one line patch in STR#2366 fixes this problem.
Making this STR a dupe of 2366 to link the two.
When 2366's patch is applied and closed, this one should be closed too.
