• .: Repeat the last command
• Ctrl-i (in a text box): Open the text in an external editor (requires native Tridactyl installation)
• start: Navigate forward/backward through paginated pages (e.g., search results, multi-part articles)

• Case Sensitivity: Hint characters (when using f or F) should be typed in lowercase.
• Firefox Keybinds: Tridactyl cannot override some native Firefox key combinations (e.g., Ctrl-T for new tab, Ctrl-W to close tab).
• Configuration: You can customize keybindings and settings extensively using the command line (e.g., :bind, :set).
• : (Command Mode): Many actions are available as “ex-commands” by typing a colon first.
• Ctrl-v: Bypass Tridactyl bindings for the next single keystroke (useful for passing a key directly to the website).
