Snippet Vault

Save code you reuse and drop it into any file in two keystrokes. Snippet Vault also ships with a small library of ready-made lab programs.

Features

Save a selection (or the whole file if nothing is selected) under a name you choose.
Insert any saved snippet at your cursor, replacing the current selection.
Open as new file to start a fresh editor with the snippet's language already set.
Delete snippets you no longer need.
Your snippets sync across machines when VS Code Settings Sync is on.
