Why do percentage signs (%) in my snippet text not appear when it is expanded?
The percentage sign (%) is a special macro character in TextExpander snippets. It is used to indicate that date, time, or other information should be substituted at that point in your snippet.
To get a % to expand, just put %% in your snippet.
For example, if you want your snippet text to be "50% discount", enter it as "50%% discount".
