The original developer seems to be busy right now.

Press , (comma) on your keyboard to show hints for all links, buttons, text fields and other things you can click or focus.

Press . (period) instead to open links in new tabs when they are clicked.

These shortcuts can be changed in the add-on options.

Hints will be automatically triggered when possible. You can disable this in the add-on options.

Press Escape to hide the hints.
