Document Alacritty's features

# Features
This document gives an overview over Alacritty's features beyond its terminal
emulation capabilities. To get a list with supported control sequences take a
look at [Alacritty's escape sequence support](./escape_support.md).
## Vi Mode
The vi mode allows moving around Alacritty's viewport and scrollback using the
keyboard. It also serves as a jump-off point for other features like search and
opening URLs with the keyboard. By default you can launch it using
<kbd>Ctrl</kbd> <kbd>Shift</kbd> <kbd>Space</kbd>.
### Motion
The cursor motions are setup by default to mimic vi, however they are fully
configurable. If you don't like vi's bindings, take a look at the [configuration
file] to change the various movements.
### Selection
One useful feature of vi mode is the ability to make selections and copy text to
the clipboard. By default you can start a selection using <kbd>v</kbd> and copy
it using <kbd>y</kbd>. All selection modes that are available with the mouse can
be accessed from vi mode, including the semantic (<kbd>Alt</kbd> <kbd>v</kbd>),
line (<kbd>Shift</kbd> <kbd>v</kbd>) and block selection (<kbd>Ctrl</kbd>
<kbd>v</kbd>). You can also toggle between them while the selection is still
active.
## Search
Search allows you to find anything in Alacritty's scrollback buffer. You can
search forward using <kbd>Ctrl</kbd> <kbd>Shift</kbd> <kbd>f</kbd> and
backward using <kbd>Ctrl</kbd> <kbd>Shift</kbd> <kbd>b</kbd>.
### Vi Search
In vi mode the search is bound to <kbd>/</kbd> for forward and <kbd>?</kbd> for
backward search. This allows you to move around quickly and help with selecting
content. The `SearchStart` and `SearchEnd` keybinding actions can be bound if
you're looking for a way to jump to the start or the end of a match.
### Normal Search
During normal search you don't have the opportunity to move around freely, but
you can still jump between matches using <kbd>Enter</kbd> and <kbd>Shift</kbd>
<kbd>Enter</kbd>. After leaving search with <kbd>Escape</kbd> your active match
stays selected, allowing you to easily copy it.
Add regex terminal hints This adds support for hints, which allow opening parts of the visual buffer with external programs if they match a certain regex. This is done using a visual overlay triggered on a specified key binding, which then instructs the user which keys they need to press to pass the text to the application. In the future it should be possible to supply some built-in actions for Copy/Pasting the action and using this to launch text when clicking on it with the mouse. But the current implementation should already be useful as-is. Fixes #2792. Fixes #2536.

## Hints
Terminal hints allow easily interacting with visible text without having to
start vi mode. They consist of a regex that detects these text elements and then
Add copy/paste/select hint actions This adds some built-in actions for handling hint selections without having to spawn external applications. The new actions are `Copy`, `Select` and `Paste`.

either feeds them to an external application or triggers one of Alacritty's
built-in actions.

Add vi/mouse hint highlighting support This patch removes the old url highlighting code and replaces it with a new implementation making use of hints as sources for finding matches in the terminal.
2021-04-12 23:24:42 -04:00
Hints can also be triggered using the mouse or vi mode cursor. If a hint is
enabled for mouse interaction and recognized as such, it will be underlined when
the mouse or vi mode cursor is on top of it. Using the left mouse button or
<kbd>Enter</kbd> key in vi mode will then trigger the hint.

Hints can be configured in the `hints` and `colors.hints` sections in the
Alacritty configuration file.

## Selection expansion
After making a selection, you can use the right mouse button to expand it.
Double-clicking will expand the selection semantically, while triple-clicking
will perform line selection. If you hold <kbd>Ctrl</kbd> while expanding the
selection, it will switch to the block selection mode.
## Opening URLs with the mouse
You can open URLs with your mouse by clicking on them. The modifiers required to
be held and program which should open the URL can be setup in the configuration
file. If an application captures your mouse clicks, which is indicated by a
change in mouse cursor shape, you're required to hold <kbd>Shift</kbd> to bypass
that.
