shortcut to select word and popup autocomplete

[Ted Naleid]

The AceJump intellij plugin has a cool feature that when hitting alt combined with the jump target character will select the whole word and pop up the autocomplete box for it.

We could allow the cmd-alt-; keystroke to select the whole word (or remaining part of the word if it's not the first char in the word) as a start.

Could also look into popping up the autocomplete dialog as well, though this isn't quite as useful in ST2 as IntelliJ

this will be nice!
