insert empty (check) box: bound to a key

Oh, here's another:
o Enter one box.
o Select it.
o Go to Edit | AutoText... .
o Probably select My AutoText.
o Type a name for your entry.
o Modify the shortcut if preferred.
o Under AutoText select New.
o Click Close.

To use this, type the shortcut and press F3.

I trust this also helps.
