It's been a year or more since I initially set up snippets, so I don't remember the details. But I do know that I can currently type the prefix and it will immediately pop up with a pane of suggested expansions. I did just think of one possibility for why you're not seeing this. If you use

@

as the initial character of your snippet prefix (i.e.

@td

to automatically add today's date), Dendron might interpret the

@

as a user name? I've been meaning to go back and make all my snippets start with a

;

for precisely this reason… but so far I've just turned Dendron's user features off. 😅
