Tridactyl is a Firefox WebExtension that brings Vim-like keybindings and commands to your browser, allowing for highly efficient keyboard-only navigation. Here's a cheat sheet covering some of the most common and useful commands:

gg: Scroll to the top of the page
G: Scroll to the bottom of the page
H: Go back in history
L: Go forward in history
r: Reload page
R: Hard reload page (clears cache)
f: Enter “hint mode” to follow a link (type the displayed hint characters)
F: Enter “hint mode” to open a link in a background tab
gF: Repeatedly open links in hint mode until you hit `<Escape>`
gi: Focus the last-used input field on the page
yy: Copy the current page URL to the clipboard
gu: Go to the parent of the current URL
gU: Go to the root domain of the current URL
zi / zo / zz: Zoom in / zoom out / reset zoom

d: Close the current tab
u: Reopen the last closed tab (or window)
gt: Go to the next tab
gT: Go to the previous tab
g^ / g0: Go to the first tab
g$: Go to the last tab
b: List all open tabs (you can type to filter and navigate the list)
ga: Go to the tab playing audio

o / O: Open a URL (or default search) in the current tab (O pre-loads current URL)
t / T: Open a URL (or default search) in a new tab (T pre-loads current URL)
w / W: Open a URL (or default search) in a new window (W pre-loads current URL)
p / P: Open clipboard content in the current/new tab
s / S: Perform an engine search in the current/new tab

: Activate the command line
- `:help [command]`: Get help on a specific command
- `:set [setting] [value]`: Set a Tridactyl setting
- `:bind [key_sequence] [ex_command]`: Bind a key sequence to an ex-command
- `:tabopen [URL]`: Open a URL in a new tab
- `:winopen [URL]`: Open a URL in a new window
- `:mkt ~/filename.rc`: (Requires native Tridactyl installation) Save current configuration to a file.
- `:viewconfig nmaps`: View current normal mode keybindings
- `:tabdetach`: Detach the current tab into a new window

v: Enter visual mode
- h / l: Expand/reduce selection by one character
- 0 / $: Expand selection to beginning/end of line
- e / b: Expand selection to next/previous word
- j / k: Expand selection to next/previous line
- =: Expand progressively to whole page
- s / S: Search for selection (current/new tab)
- y: Yank (copy) selection to clipboard

;i / ;I: Open an image (current/new tab)
;s / ;a: Save/save-as the linked resource
;S / ;A: Save/save-as the selected image
;p.: Copy an element's text to the clipboard
;P.: Copy an element's title/alt text to the clipboard
;y: Copy an element's link URL to the clipboard
;#: Copy an element's anchor URL to the clipboard
;r: Read the element's text with text-to-speech
;k: Delete an element from the page
;;: Focus an element

Shift + Insert: Enable/disable “ignore mode” (pass all keys to the website)
Ctrl + Alt + Escape: Temporarily disable/enable Tridactyl (similar to ignore mode)
.: 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).

This cheat sheet provides a solid foundation for using Tridactyl. For a complete and up-to-date list of commands and their descriptions, consult the official Tridactyl documentation by typing `:help` in your browser with Tridactyl installed.
