[TxMt] Keyboard shortcut for Tabs to Spaces / Spaces to Tabs

[Trevor Harmon]

Tabs to Spaces and Spaces to Tabs are without keyboard shortcuts.  
Allan Odgaard said he would consider giving them shortcuts if he knew  
what shortcuts to use. [1]

I'm thinking Command+Option+Shift+S for Tabs to Spaces and Command 
+Option+Shift+T for Spaces to Tabs. These seem to be available (but I  
have no idea how to be sure).

Does anyone have a better suggestion?
