--- consists of either a string trigger word and its snippet text, or a string
--- lexer name (from the *lexers/* directory) with a table of trigger words and
--- snippet texts. When searching for a snippet to insert based on a trigger
--- word, Textadept considers snippets in the current lexer to have priority,
