/** # Tridactyl help page
Use `:help <excmd>` or scroll down to show [[help]] for a particular excmd.
The default keybinds can be found [here](/static/docs/modules/_src_config_.html#defaults) or all active binds can be seen with `:viewconfig nmaps`.
You can also view them with [[bind]]. Try `bind j`.
For more information, and FAQs, check out our [readme][4] on github.
Tridactyl is in a pretty early stage of development. Please report any
issues and make requests for missing features on the GitHub [project page][1].
You can also get in touch using Matrix, Gitter, or IRC chat clients:
[![Matrix Chat][matrix-badge]][matrix-link]
[![Gitter Chat][gitter-badge]][gitter-link]
[![Freenode Chat][freenode-badge]][freenode-link]
All three channels are mirrored together, so it doesn't matter which one you use.
## How to use this help page
We've hackily re-purposed TypeDoc which is designed for internal documentation. Every function (excmd) on this page can be called via Tridactyl's command line which we call "ex". There is a slight change in syntax, however. Wherever you see:
`function(arg1,arg2)`
You should instead type
`function arg1 arg2` into the Tridactyl command line (accessed via `:`)
A "splat" operator (...) means that the excmd will accept any number of space-delimited arguments into that parameter.
You do not need to worry about types. Return values which are promises will turn into whatever they promise to when used in [[composite]].
At the bottom of each function's help page, you can click on a link that will take you straight to that function's definition in our code. This is especially recommended for browsing the [config](/static/docs/modules/_src_config_.html#defaults) which is nigh-on unreadable on these pages.
## Highlighted features:
- Press `b` to bring up a list of open tabs in the current window; you can
type the tab ID or part of the title or URL to choose a tab
- Press `Shift` + `Insert` to enter "ignore mode". Press `Shift` + `Insert`
again to return to "normal mode". `<C-A-backtick>` also works both ways.
- Press `f` to start "hint mode", `F` to open in background (note: hint
characters should be typed in lowercase)
- Press `o` to `:open` a different page
- Press `s` if you want to search for something that looks like a domain
name or URL
- [[bind]] new commands with e.g. `:bind J tabnext`
- Type `:help` to see a list of available excmds
- Use `yy` to copy the current page URL to your clipboard
- `[[`and `]]` to navigate through the pages of comics, paginated
articles, etc
- Pressing `ZZ` will close all tabs and windows, but it will only "save"
them if your about:preferences are set to "show your tabs and windows
from last time"
- Change theme with `colours default|dark|greenmat|shydactyl`
There are some caveats common to all webextension vimperator-alikes:
- To make Tridactyl work on addons.mozilla.org and some other Mozilla domains, you need to open `about:config`, run [[fixamo]] or add a new boolean `privacy.resistFingerprinting.block_mozAddonManager` with the value `true`, and remove the above domains from `extensions.webextensions.restrictedDomains`.
- Tridactyl can't run on about:\*, some file:\* URIs, view-source:\*, or data:\*, URIs.
- To change/hide the GUI of Firefox from Tridactyl, you can use [[guiset]]
with the native messenger installed (see [[native]] and
[[installnative]]). Alternatively, you can edit your userChrome yourself.
There is an [example file](2) available in our repository.
If you want a more fully-featured vimperator-alike, your best option is
[Firefox ESR][3] and Vimperator :)

* * `http://example.com` -> (`-t exa peta`) -> `http://petample.com`
*
* * Regex replacment mode: `urlmodify -r <regexp> <new> [flags]`
*
* Replaces the first match of the `regexp` with `new`. You can use
* flags `i` and `g` to match case-insensitively and to match
* all instances respectively
* * `http://example.com` -> (`-r [ea] X g`) -> `http://XxXmplX.com`
*
* * Query replace mode: `urlmodify -q <query> <new_val>`
*
* Replace the value of a query with a new one:
* * `http://e.com?id=foo` -> (`-q id bar`) -> `http://e.com?id=bar
*
* * Query delete mode: `urlmodify -Q <query>`
*
* Deletes the given query (and the value if any):
* * `http://e.com?id=foo&page=1` -> (`-Q id`) -> `http://e.com?page=1`
*
* * Graft mode: `urlmodify -g <graft_point> <new_path_tail>`
*
* "Grafts" a new tail on the URL path, possibly removing some of the old
* tail. Graft point indicates where the old URL is truncated before adding
* the new path.
*
* * `graft_point` >= 0 counts path levels, starting from the left
* (beginning). 0 will append from the "root", and no existing path will
* remain, 1 will keep one path level, and so on.
* * `graft_point` < 0 counts from the right (i.e. the end of the current
* path). -1 will append to the existing path, -2 will remove the last path
* level, and so on.
*
* ```text
* http://website.com/this/is/the/path/component
* Graft point: ^ ^ ^ ^ ^ ^
* From left: 0 1 2 3 4 5
* From right: -6 -5 -4 -3 -2 -1
* ```
*
* Examples:
*
* * `http://e.com/issues/42` -> (`-g 0 foo`) -> `http://e.com/foo`
* * `http://e.com/issues/42` -> (`-g 1 foo`) -> `http://e.com/issues/foo`
* * `http://e.com/issues/42` -> (`-g -1 foo`) -> `http://e.com/issues/42/foo`
* * `http://e.com/issues/42` -> (`-g -2 foo`) -> `http://e.com/issues/foo`
*
* @param mode The replace mode:
* * -t text replace
* * -r regexp replace
* * -q replace the value of the given query
* * -Q delete the given query
* * -g graft a new path onto URL or parent path of it
* @param replacement the replacement arguments (depends on mode):
* * -t <old> <new>

* * -q <query> <new_val>
* * -Q <query>
* * -g <graftPoint> <newPathTail>

- `bind j scrollline 20`

You can view binds by omitting the command line:

- `bind k`
You can bind to modifiers and special keys by enclosing them with angle brackets, for example `bind <C-\>z fullscreen`, `unbind <F1>` (a favourite of people who use TreeStyleTabs :) ), or `bind <Backspace> forward`.
Modifiers are truncated to a single character, so Ctrl -> C, Alt -> A, and Shift -> S. Shift is a bit special as it is only required if Shift does not change the key inputted, e.g. `<S-ArrowDown>` is OK, but `<S-a>` should just be `A`.
You can view all special key names here: https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key/Key_Values
