Description of problem:
If you choose Mod1-Shift_L (the default) as the keyboard layout switch hotkey,
it only switches the keyboard layout if you hold alt, press left shift, release
shift and then release alt. If you release alt before shift, it seems to revert
to the original state. Is this intentional, just to avoid accidental switching?
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Press Alt and hold
Actual Results: Keyboard layout is unchanged.
Expected Results: I'd expect it to change.
I can see that this may well be a feature, but it can be annoying if you release
both keys almost at the same time. It could try to time the events to avoid
unintended changes, e.g., if the time between the pressing of the second key and
the releasing either key is larger than the interval between the pressing of
both keys, then it's an intended layout switch. This helps avoid pressing the
shift right before releasing the alt when a layout switch is not intended.
This should at least be copied upstream to bugzilla.gnome.org
Also, if you use the keyswitcher applet - could you try some of the
others on the internet, such as http://gswitchit.sourceforge.net/
and see if we should use those instead?
This applet seems to lack upstream love.
I have no idea if this is a bug or intentional...
