bind is a console command available in all Source Source games.

English (en)

It is used to bind a key to one or several other commands. Typically, when keys are bound, the corresponding bind command is stored in config.cfg, which is ran when the engine starts, leading to binds staying active between sessions, unless config.cfg is set to read-only.


Basic Syntax

The basic syntax for the command is as follows:

bind <key> [command]

For example, after running bind 1 slot1, pressing 1 would execute the command slot1. Additionally, binding a key to a semicolon-separated list of commands in quotation marks would cause all commands to be executed, because everything within quotation marks is interpreted as a single argument. After running bind mouse1 "slot1; unbind mouse1", then pressing mouse1, slot1 would be run, followed by unbind mouse1.

+/- Commands

If the first character in the command/string that the key is bound to is +, then after releasing the key, the same string of commands is executed, except the first character is replaced with -. For example, running bind w +forward will cause +forward to be run when w is pressed, then -forward to be run when w is unpressed. Consequently, there are some cases where the result of pressing a key are different from what is intuitive. Running bind w "+forward; +attack" will cause +forward;+attack to be run when w is pressed, but causes -forward;+attack to be run when w is unpressed, causing +attack to be run, rather than -attack. The alias command can be used in conjunction with bind to yield different results. To make the W key instead run +forward; +attack when pressed, and run -forward; -attack when unpressed, the following commands can be used:

alias +w_pressed "+forward; +attack" alias -w_pressed "-forward; -attack" bind w +w_pressed
