Scintilla defines key shortcuts for some editing
actions (i.e. CTRL+D for duplicate line) in KeyMap.cxx.
These shortcuts can be disabled through a CmdKeyClear.
Unfortunately these shortcut keys are never accessable
under wxGTK by the menu, etc. possibly through another
bug there. Since Scintilla library shouldn't enforce
the use of any key for normal editing actions (besides
the standard key navigation), these keys shouldn't be
defined. This is no problem since any user of the
Scintilla library can defined them through CmdKeyAssign.
This patch is against KeyMap.cxx in wxGTK but it should
be easy to apply it in Scintilla. It removes the most
crititcal key shortcuts.
