I believe that the AutoText feature in Studio is a useful one. Nevertheless, my experience has shown that many users do not use it. My suggestion is to make AutoText truly automatic so that everyone uses it straight away. Create a dialog box for AutoText which, for example, has two configurable settings:

Minimum length of entries  = 12
Minimum occurrence of entries = 3

AutoText would then work this way:

Studio automatically monitors everything you type. As soon as you have typed in a word that has at least 12 characters three times within a file, it is added automatically to your list of AutoText terms.

If users gets too few or to many entries, they can change the settings accordingly. In addition, it would be helpful if AutoText would kick in sooner, not after typing in at least 4 characters.
