From The App

This is the basic way to use snippets. You can just open the app by using the hotkey (by default CMD + Shift + Space), find your snippet, and press Enter to expand it. Alternatively, you can double-click on the snippet to expand it.

The benefit of using this approach is that you can see all your snippets in one place and easily find the one you need, seeing the preview of the snippet. You don't have to remember its name or keyword.
