Use a macro to deselect the text then execute the command.  I have a 
"Select Nothing" macro that is:

   moveRightAndModifySelection:
   moveLeft:

(Record it by typing "shift-Right" then "Left".)  This places the cursor 
at the beginning of the selection then clears the selection.  Just record 
a macro with those strokes and the "Smart Home" command, save the macro, 
and bind it to the Home key.

(As an aside...  I'm surprised I can't find a "clearSelection:" action. 
Anyone know of one that's better than this hack?)

It would, of course, be better to just move the cursor without modifying 
the selection.  Unfortunately, the way commands are implemented there's no 
way to simply move the cursor without inserting text as a snippet.  Any 
selection is going to be replaced by that insertion.

Which brings us to another problem with this command.  Since it's actually 
doing an insert operation the buffer gets marked as modified, even if no 
other changes have been made.  I'd love to have a way to simply move the 
cursor without the insert operation.  Here's to a richer API in 2.0!
