It's bound to ), ], and } right?  It means that hitting any of those  
keys doesn't necessarily insert that character.  Instead, it is smart  
enough to insert ), ], or } as appropriate, to balance the previous  
(, [, or {.

Type on one line:

a       b

Then move the cursor to somewhere between the "a" and the "b", hit  
Esc-Space or Meta-Space, and it should collapse the space to:

a b
