has dropped support for legacy add-ons. Vim Vixen is a new choice for Vim users
since it uses the WebExtensions API.
## Basic usage
### Keymaps
Keymaps are configurable in the add-on's preferences by navigating to `about:addons` and selecting "Extensions".
The default mappings are as follows:
#### Console
- <kbd>:</kbd>: open the console
- <kbd>o</kbd>, <kbd>t</kbd>, <kbd>w</kbd>: open a page in the current tab, a new tab, or new window
- <kbd>O</kbd>, <kbd>T</kbd>, <kbd>W</kbd>: similar to <kbd>o</kbd>, <kbd>t</kbd>, <kbd>w</kbd>, but using the current URL
- <kbd>b</kbd>: select tabs by URL or title
- <kbd>a</kbd>: add the current page to your bookmarks
See the [console commands](#console-commands) section for a more detailed description.
#### Tabs
- <kbd>d</kbd>: delete the current tab and select the tab to its right
- <kbd>D</kbd>: delete the current tab and select the tab to its left
- <kbd>!</kbd><kbd>d</kbd>: delete a pinned tab
- <kbd>u</kbd>: reopen a close tab
- <kbd>r</kbd>: reload the current tab
- <kbd>R</kbd>: reload the current tab, bypassing the cache
- <kbd>K</kbd> or <kbd>g</kbd><kbd>T</kbd>: select the previous tab
- <kbd>J</kbd> or <kbd>g</kbd><kbd>t</kbd>: select the next tab
- <kbd>g</kbd><kbd>0</kbd>: select the first tab
- <kbd>g</kbd><kbd>$</kbd>: select the last tab
- <kbd>Ctrl</kbd>+<kbd>6</kbd>: open the previously-selected tab
- <kbd>z</kbd><kbd>p</kbd>: pin the curent tab tab
- <kbd>z</kbd><kbd>d</kbd>: duplicate the current tab
#### Scrolling
- <kbd>k</kbd>: scroll up
- <kbd>j</kbd>: scroll down
- <kbd>h</kbd>: scroll left
- <kbd>l</kbd>: scroll right
- <kbd>Ctrl</kbd>+<kbd>U</kbd>: scroll up half a page
- <kbd>Ctrl</kbd>+<kbd>D</kbd>: scroll down half a page
- <kbd>Ctrl</kbd>+<kbd>B</kbd>: scroll up a page
- <kbd>Ctrl</kbd>+<kbd>F</kbd>: scroll down a page
- <kbd>g</kbd><kbd>g</kbd>: scroll to the top of a page
- <kbd>G</kbd>: scroll to the bottom of a page
- <kbd>0</kbd>: scroll to the leftmost part of a page
- <kbd>$</kbd>: scroll to the rightmost part of a page
- <kbd>m</kbd>: set a mark for the current position
- <kbd>'</kbd>: jump to a marked position
Lowercase marks (`[a-z]`) store the position of the current tab. Uppercase and
numeric marks (`[A-Z0-9]`) store the position and the tab.
#### Zoom
- <kbd>z</kbd><kbd>i</kbd>: zoom in
- <kbd>z</kbd><kbd>o</kbd>: zoom out
- <kbd>z</kbd><kbd>z</kbd>: zoom neutral (reset)
#### Navigation
- <kbd>f</kbd>: follow links in the page in the current tab
- <kbd>F</kbd>: follow links in the page in a new tab
- <kbd>H</kbd>: go back in history
- <kbd>L</kbd>: go forward in history
- <kbd>[</kbd><kbd>[</kbd>, <kbd>]</kbd><kbd>]</kbd>: find a link to the previous/next page and open it
- <kbd>g</kbd><kbd>u</kbd>: go to the parent directory
- <kbd>g</kbd><kbd>U</kbd>: go to the root directory
- <kbd>g</kbd><kbd>i</kbd>: focus the first input field
Vim Vixen can be configured to follow links opened in tabs in the background
instead of switching to a new tab immediately. To do this, you'll need to update
the config file: change the `"background"` property of the `"follow.start"`
action to `true`, e.g.:
```json
{
"keymaps": {
"F": { "type": "follow.start", "newTab": true, "background": true }
}
}
```
#### Misc
- <kbd>y</kbd>: copy the URL of the current tab to the clipboard
- <kbd>p</kbd>: open the clipboard's URL in the current tab
- <kbd>P</kbd>: open the clipboard's URL in new tab
- <kbd>Shift</kbd>+<kbd>Esc</kbd>: enable or disable the add-on in the current tab
- <kbd>/</kbd>: start searching for text in the page
- <kbd>n</kbd>: find the next search result in the page
- <kbd>N</kbd>: find the previous search result in the page
- <kbd>g</kbd><kbd>f</kbd>: view the source of the current tab
### Console commands
Vim Vixen provides a console for `ex`-style commands, similar to Vimperator.
Open the console with <kbd>:</kbd>. Or populate it with initial values using
<kbd>o</kbd>/<kbd>O</kbd>, <kbd>t</kbd>/<kbd>T</kbd>, or
<kbd>w</kbd>/<kbd>W</kbd>.
#### `:open`
The `:open` command operates two different ways, depending on the parameter.
When the parameter is a URL, it's opened in the current tab.
```
:open http://github.com/ueokande
```
Otherwise, the current tab opens a search page with the supplied string (defaults to Google).
```
:open How to contribute to Vim-Vixen
```
To use a search engine other than the default, specify the search engine to use as the first parameter.
```
:open yahoo How to contribute to Vim-Vixen
```
To adjust the default search-engine and add/remove search engines, see the [search engines](#search-engines) section.
#### `:tabopen`
Open a URL or search-engine query in a new tab.
#### `:quit` or `:q`
Close the current tab.
#### `:quitall` or `:qa`
Close all tabs.
#### `:bdelete`
Close a certain tab.
You can add `!` to the end of the command to close a tab even if it is pinned:
To get Vim Vixen, install it from [Firefox add-ons][AMO].
```
:bdelete!
```
#### `:bdeletes`
Close tabs matching the specified keywords.
You can add `!` to the end of the command to close pinned tabs:
```
:bdeletes!
```
#### `:winopen`
Open a URL or search-engine query in a new window.
#### `:buffer`
Select tabs by URL or title keywords.
#### `:addbookmark`
Create a bookmark from the current URL.
```
:addbookmark My bookmark title
```
The keymap <kbd>a</kbd> is a convenient way to create a bookmark for the
current page. It populates the console with `:addbookmark` and the title of
the current page.
#### `:set`
The `:set` command can be used to temporarily override properties in the
console. See the [properties](#properties) section for more details on
the available properties.
### Properties
Vim Vixen can be configured by defining settings in a JSON document, e.g.:
```json
{
"properties": {
"complete": "sbh"
}
}
```
Properties can be temporarily overridden by using the `:set` command in the
console.
The following properties are available:
#### `smoothscroll`
Enable/disable smooth scrolling.
```
:set smoothscroll " enable smooth scrolling
:set nosmoothscroll " disable smooth scrolling
```
#### `hintchars`
Set hint characters.
```
:set hintchars=0123456789
```
#### `complete`
Set completion items on `open`, `tabopen`, and `winopen` commands.
The allowed value is character sequence of `s`, `b`, or `h`.
Hit <kbd>Tab</kbd> or <kbd>Shift</kbd>+<kbd>Tab</kbd> to select an item from the completion list.
Each character represents the following:
- `s`: search engines
- `b`: bookmark items
- `h`: history items.
```
:set complete=sbh
```
### Search engines
Vim Vixen supports searching with search engines such as Google and Yahoo.
You can configure search engines, including the default search engine, in the add-on's preferences.
The URLs specified in `"engines"` must contain a `{}`-placeholder, which will be
replaced with the search keyword parameters of the command.
```json
{
"search": {
"default": "google",
"engines": {
"google": "https://google.com/search?q={}",
"yahoo": "https://search.yahoo.com/search?p={}",
"bing": "https://www.bing.com/search?q={}",
"duckduckgo": "https://duckduckgo.com/?q={}",
"twitter": "https://twitter.com/search?q={}",
"wikipedia": "https://en.wikipedia.org/w/index.php?search={}"
}
}
}
```
### Blacklist
The blacklist allows you to disable the plugin for certain pages by URL patterns.
For instance, you could use `"*.slack.com"` to disable the plugin on all Slack channels.
In addition, you can also specify path patterns, such as `"example.com/mail/*"`.
```json
{
"blacklist": [
"*.slack.com",
"example.com/mail/*"
]
}
```
You can toggle Vim Vixen between disabled and enabled with
<kbd>shift</kbd>+<kbd>Esc</kbd>.

# Vim Vixen
Vim Vixen is a Firefox add-on which allows you to easily navigate the web by
keyboard. Since version 57, Firefox has migrated to the WebExtensions API and
has dropped support for legacy add-ons. Vim Vixen is a new choice for Vim users
since it uses the WebExtensions API.
## Getting started
### Install Vim Vixen
Vim Vixen is supported on Firefox 60 ESR. Please latest version of stable ESR
from the [download page](https://www.mozilla.org/en-US/firefox/).
You can install Vim Vixen from [Firefox add-ons (addons.mozilla.org)][AMO], and
manage installed addon-ons on Firefox preferences `about:preferences`.
### Quick start
After installation, you can control Firefox with vim-like keymaps. To scroll a
page in the browser, press <kbd>k</kbd>, <kbd>j</kbd>, <kbd>h</kbd> and
<kbd>l</kbd> keys. You can scroll to the top or the bottom of a page by
<kbd>g</kbd><kbd>g</kbd> and <kbd>G</kbd>.
To select a left and right of current tab, use <kbd>K</kbd> and <kbd>J</kbd>
respectively. To close current tab, use <kbd>d</kbd> and to restore closed
tabs, use <kbd>u</kbd>.
To open a link, press <kbd>f</kbd> to enter the **follow mode** to select a
link. Then you can select links by alphabetic keys.
See also [Keymaps](./keymaps.html) for more detailed of keymaps.
### Using commands
Vim Vixen supports command line to run commands that control tabs and opens a
tab. To open command line, press <kbd>:</kbd>.
To open a tab with URL, use `open` command as the following:
```
:open https://github.com/ueokande/vimvixen
```
or search keywords with search engine (such as Google) like:
```
:open How to use Vim
```
You can see completed commands on [Console commands](./console_commands.html).
