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.
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 Ctrl Shift Space.
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.
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 v and copy it using y. All selection modes that are available with the mouse can be accessed from vi mode, including the semantic (Alt v), line (Shift v) and block selection (Ctrl v). You can also toggle between them while the selection is still active.
While in vi mode you can open URLs using the Enter key. If some text is recognized as a URL, it will be underlined once you move the vi cursor above it. The program used to open these URLs can be changed in the configuration file.
Search allows you to find anything in Alacritty's scrollback buffer. You can search forward using Ctrl Shift f and backward using Ctrl Shift b.
In vi mode the search is bound to / for forward and ? 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.
During normal search you don't have the opportunity to move around freely, but you can still jump between matches using Enter and Shift Enter. After leaving search with Escape your active match stays selected, allowing you to easily copy it.
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 Ctrl while expanding the selection, it will switch to the block selection mode.
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 Shift to bypass that.
