I'm having a weird problem with version 1.6.6b4.  (This is my first version, so it might happen in older versions too)  On my MacBook Pro, I have remapped the enter key to option.  This works perfectly, except that one shortcut does not work.  The enter key (mapped as option)+right command+the right arrow key does not work.  It works with the left arrow key, it works with the left command, and it works with the left option.  Those exact three keys seem to be the only ones that don't work.  Anyone have any ideas why this is?
