[Bug 213579] New: ignores keypad when numlock is off

https://bugs.kde.org/show_bug.cgi?id=213579

           Summary: ignores keypad when numlock is off
           Product: konsole
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel@...
        ReportedBy: svivanov@...


Version:            (using KDE 4.3.3)
OS:                Linux
Installed from:    Ubuntu Packages

A 104-key PC keyboard has a 'numeric keypad' section that produces digits when
NumLock is on, and cursor movement keys (arrows etc) when NumLock is off. This
keypad does not work under konsole when NumLock is off - the keys are just
ignored (unless you hold a modifier like shift or alt). Tested this on two
x86-64 Linux boxes (one is a generic PC desktop and another is a Toshiba
laptop).

Expected behavior: when NumLock is off, these keys should produce the same
escape sequences as the PC XT cursor movement keys.

Using a recipe found in someone's blog, I fixed this for myself by the patch
included below. This is applied to the file 'default.keytab' found in
/usr/share/kde4/apps/konsole upon installation.

I added these entries to the default keyboard layout at some point but
discovered that it caused problems with Vim.  My notes from the code change
were:

Disable application keypad support in the default key bindings file as,
although it
produces the correct key codes as tested using 'vttest', it breaks Vim - which
enables application key pad by default.

Those entries were for the case of numlock ON if I understand correctly.
What I added is for numlock OFF, and the codes are the same as for
ordinary arrow keys.

I tried to run vim with my customized keytab file and did not observe
symptoms described in Bug 183076. (However I am not a vi user and cannot
tell vi bugs from features.)
