Description Gabriel Schulhof 2005-01-09 22:50:20 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux ppc; en-US; rv:1.7.5)
Gecko/20041220 Fedora/1.7.5-2

Description of problem:
Apple iBook laptop keyboards do not have an "Insert" key.  These
to some of the xkb configuration files will cause the Mod4+Backspace
to produce a clean "Insert".  This can then be used in text editors
and word
processors for toggling insert/overtype mode.

This modification should go completely unnoticed by people who do have an
"Insert" key. I tested it on a computer with an "Insert" key (a
regular IBM PC
compatible) and it didn't affect it at all. "Mod4+Insert" results in
just that,
and "Mod4+Backspace" results in "Insert".

I suppose the only side effect is that the user cannot assign
to anything in, say, the "Keyboard Shortcuts" applet, because trying
to do so
would cause "Insert" to be bound to something, and not "Mod4+Backspace".

incorrect, please change it accordingly.
