Is there a way you can remove the preview for Autotext/Quick Parts? It just
takes up a lot of the screen and I'd like to use the space to list more
entries.
If you're referring to the preview in the Building Blocks Organizer dialog, the
answer is no. And, unfortunately, the dialog isn't resizable, so you can't
display a longer section of the list.
As a slight aid to quick navigation, you can press the letter key for the first
letter of the name of an item you want. The selector will jump to the next item
that starts with that letter. Press the same letter repeatedly to keep skipping
through the list.
The alternative, if you have the necessary knowledge and free time, is to build
a userform that presents just the list.
