Hi,

Thanks for WT-Team to all efforts. Hope that these minor adjustment can 
be implemented during ongoing week.

Please when adding this XSWAP-shortcut, it would be highly recommended 
not to ask any confirmation from user. Now when using mouse-menu to get 
swap, there are extra question which needs user action to accept that 
action. It is not needed in shortcut, because it will slowdown swapping 
procedure too much. User typing xswap should be highly aware what is 
going to happen without any extra popups.
