    How do I use Fangs?

    Adding new Bangs:

    • Fill out all info in the Editor and click Save!
    • The "Identifier" is what you'll use to activate the bang in your searches.
    • The "Base Link" is where you want to go when you don't include any search terms.
    • The "Search Link" is where you want to go when you do include something to search for, and the link must have "{{bang}}" in it to insert your search text.

    Editing existing Bangs:

    • Click on the Bang from the "Your Bangs" list to insert it into the editor.
    • Editing a Bang with an Identifier that already exists will overwrite it with the new one.

    Removing Bangs:

    • Click on the Bang you want to remove and then click the Remove button.
