           Summary: arrow key remapping via X11 mechanisms does not seem
                    to work
           Product: kde
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: tmbdev at gmail.com


Version:           unspecified (using KDE 4.5.1) 
OS:                Linux

I use xmodmap to remap some keys.  In particular, I map arrow keys to a
combination of Mode_switch and letters.  This works in Gnome and X11 apps, but
it doesn't work in KDE apps; KDE apps just seem to ignore the arrow key
mappings; they do pick up non-arrow key mappings.

Reproducible: Always

Steps to Reproduce:
Run the script below.  Use Mode_switch + l to attempt to move the cursor right.

Actual Results:  
Nothing happens.

Expected Results:  
Cursor should move to the right.

Here is my guess at a possible source of this problem.  Arrow keys in OS X are
not treated like other keys and keyboard remapping doesn't work for them on OS
X (this is a deficiency on OS X that serves no purpose).  Some cross-platform
apps and toolkits have added workarounds for OS X that break arrow key handling
on Linux (and probably Windows).

Whatever the source of the problem, OS X should respect and correctly implement
standard X11 keyboard mappings.
