Additional trick to save one keystroke: Remove the reference to the standard code snippets in the snippet manager.

I've changed the shortcut for evoking the snippet lookup to Ctrl < and now have to type Ctrl < tt Enter. So I have an additional 3 keystrokes next to my shortcut.

Why does this help: If you only have one folder that contains snippets for your langauge, they don't show up ;-)

Of course this won't work for everybody. But still ...

Also: If you need those code snippets, consider pushing (copying) them to your own snippet.
