If you’ve used the Type tools in Photoshop Elements 11, you’ve probably noticed that as soon as you commit your text (by clicking the green checkmark or pressing Enter/Return), suddenly the Type tool is gone and the Move tool is active instead. If you want to edit your type, you have to go back over to the Tools panel and click it again.
Adobe reasons that most people will want to position their text once they’ve created it, which is why they made this change from older versions where you had the Type tool till you yourself clicked on a different tool. If you don’t like the new behavior, it’s very easy to change it, although it’s not obvious how to do it.
Just go to the Editor preferences->General, and turn off this checkbox:
From now on, the Type tool stays active until you change to another tool.
