           Summary: Shortcuts key "Patch Tab" cannot be rebound in
                    shortcuts.ini
           Product: GtkRadiant
           Version: 1.2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P3
         Component: editor

It ignores all attempts to reassign it.  This is tested with 1.2, but a fix was
found, and the problem seems to persist in the 1.3 CVS tree.

This is due to Patch Tab showing up more than once in mainframe.cpp at different
points: once in the g_Commands[] array, and once in the create_menu_item list. 
It also shows up twice in help->shortcuts list as well.

Removing the redundancies will make patch tab behave properly.
