Opposite of CTRL+D in Sublime Text 2
Solution 1:
CTRL+U
Quick Add Next
To add the next occurrence of the current word to the selection, use Quick Add Next, which is bound to Ctrl+D on Windows and Linux, or Command+D on OS X.
Again, if you go too far, use Undo Selection (Ctrl+U, or Command+U on OS X) to step backwards.
