[Kde-accessibility] Mouse emulation on/off

[Bill Haneman]

Hi Chris:

The key sequence associated with MouseKeys isn't determined by KDE.  
MouseKeys is a feature provided by the XKB X Server extension.  A fair 
bit of thought went into the "usual" choice of keybinding used.

The exact key sequence used is actually determined by the xkb keyboard 
map that you're using.  There is a special X KeySym, 
XK_Pointer_EnableKeys.  The "de facto standard" for this according to 
the XKB documentation is Shift+Alt+NumLock.  It shouldn't matter whether 
the shift and alt keys are the left or right=hand ones, as long as they 
generate the correct keysyms (possibly your right Alt key is mapped to 
something other than 'Alt' ?).

You probably can imagine why making NumLock alone provide MouseKeys is 
not a good default choice for all users, and thus why it isn't defined 
in that way in the standard XKB keymaps.  It is possible to 
hack^H^H^H^Hmodify your keymap so that the XKB_Pointer_EnableKeys maps 
to some other physical keycode sequence.  Alternatively, you can write a 
utility to programmatically turn on the XKB MouseKeys Control (see 
section 10.5.1 of the XKB manual - google for XKBlib.pdf).

regards

Bill
