Reasonably often, when I’m editing a document or email, a snippet would help. But I think that I’ll never use the snippet again. So, I don’t create it. This is silly. TE certainly won’t care if I never use the snippet again. But it still bugs me.
Recently, I’ve found that in this case, I’ll go ahead and create the snippet, but give it a temporary abbreviation, like xxxx. Then next time I could use a snippet, but don’t think I’ll ever use it again, I update the text of the temporary snippet I created before. This way I get the benefit of using the snippet while I’m editing, but don’t have to worry about wasting a snippet. And I know that xxxx is the abbreviation.
