There should be a way to create one with a ctrl alt combo.
I would think creating/editing text is a common task right?
The most used shortcuts can be reached with just the left hand while keeping your right on the mouse. Activating text tool is easy enough, hit "t" then click. But after that you are forced to either reach across to the bottom right with your left hand or hit it with your right hand. Most of the other tools have an easy way to set or swap tools.
I'm being picky I know, but I've been using PS for about 10 years now and that's one of the things that kind of breaks the work flow even if it is for a few seconds.
