Auto completion - IDE

I was finding the autocomplete function for quotes “” really annoying as when I want to enclose a statement in quotes It kept putting double quotes at each end. However purley by experimintation i select the statement (double click) then press (shift+double quote) and it sorts it all out!

Does documentation exsist for this level of edditing exsist anywhere?

The editor we use is ACE; there may be useful docs here: http://ace.ajax.org/
