intellij idea - One click project tree -

is there way in intellij 12 open file in project tree 1 click? i'm coming text-mate intellij , i'd have click on item 1 time appear in editing screen.

if there benefit having click twice please allow me know, me seems redundant double click.

i'm using mac os x.

enable "autoscroll source" alternative . can find clicking on gear icon in project explorer
