1. Try, just for fun, creating your text box the way you want in a document.
2. Select it.
3. Press Alt+F3
4. Assign a name. I suggest "_myText"
5. Put it in the Text Box Gallery
6. Put it in the Building Blocks.dotx template.
7. Use the Built-In Category
8. Press OK.

In a new document, type _myt and press the F3 or Enter key.


Can you work with that?
