Bug ID: 415289
Summary: Keyboard/mouse shortcuts should map to either keycodes
or charcodes
Product: frameworks-kwindowsystem
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kdelibs-b...@kde.org
Reporter: ska...@gmail.com
Target Milestone: ---
SUMMARY
Keyboard/mouse shortcuts currently map to high level character-combinations
only E.G.: CTRL-A or META-Ж, ALT-BTN5
If more than one keyboard layout is used on a system this causes usability
problems.
STEPS TO REPRODUCE
1. Set up multiple keyboard layouts (E.G. US English and Russian)
2. Set the switching policy to "window" (this is optional, but amplifies the
problem)
3. Configure some global shortcuts, E.G.: META-$ on a US layout
4. Switch to the Russian layout
5. Hit the shortcut defined in step 3
OBSERVED RESULT
The shortcut won't run.
META-$ on a US keyboard maps to META-SHIFT-4, but on a Russian layout that maps
back to META-;
EXPECTED RESULT
The specified keyboard shortcut should always work, in every keyboard layout.

ADDITIONAL INFORMATION
Important note:
Keyboard shortcuts should not always be mapped as above.
There are certain known situations, in fact, when users do expect them to map
to keycodes(keysyms).
This is the case for CTRL-z and CTRL-y, for example for undo/redo operations.
QWERTZ vs QWERTY layout users really mean CTRL-z to match the character, not
the keycode, even if they use both and switch between them.
However, for non language or typing related actions, other combinations may be
assigned to some window-management action, like running an application or
switching a desktop, in which case is indeed the keycode, and not the
character, which should be used.
This means KDE system settings should allow to define shortcuts and ask whether
they should match characters or the physical keys on the keyboard/mouse/other
input device.
A dropdown box could let the use specify the type of matching they want for the
given shortcut.
Match [ Key Symbol [V]]
| |
| Key Symbol |
| Physical Key |
--------------
The same applies to mice/gaming mice and other buttons from input devices
There are some gaming mice which internally map button 6 to PGUP, then have
another operating mode in which button 6 becomes BACK.
This is another case when it is desirable for some shortcuts to be defined
against the low level keycode, so they just work independently of the mode the
mouse is currently set up.
