User Key Bindings

This page describes how user can update key bindings in Brackets.

Key bindings for default commands or extensions can be overridden or removed.

Currently, only key bindings for commands can be updated -- not editor bindings currently handled by the CodeMirror keymap. Key bindings cannot be modified for special commands: cut, copy, paste, undo, redo, or select all.

Quick Start

Use Debug > Open User Key Map to open the keymap.json in Brackets so it can be edited. If the file does not already exist, then it will be automatically created.

Changes to key bindings are applied immediately on File Save.

Location

The keymap.json file is located in the the user data folder. The user data folder is located at:

• Mac: ~/Library/Application Support/Brackets
• Win XP: C:\Documents and Settings\<username>\Application Data\Brackets -- (aka %appdata%\Brackets)
• Win Vista/7/8: C:\Users\<username>\AppData\Roaming\Brackets -- (aka %appdata%\Brackets)
• Linux: ~/.config/brackets -- (aka $XDG_CONFIG_HOME/brackets)

JSON Data Format

The JSON data format is:

{
    "overrides": {
        "<key>": "<command-id>"
        [, "<key>": "<command-id>"]
    }
}

Where:

<key> is a unique key. <command-id> is the command id string to assign, or null to remove a key binding.

Modifier keys are operating system specific, so on Mac use Cmd versus Ctrl on Windows. The following table lists all the valid modifier keys and other supported key names.

Windows/Linux	Mac	Notes
Ctrl	Cmd
Alt	Opt
Shift	Shift
	Ctrl	Control key only available on Mac
Up	Up	displayed as \u2191 on mac
Down	Down	displayed as \u2193 on mac
Left	Left	displayed as \u2190 on mac
Right	Right	displayed as \u2192 on mac
Backspace	Backspace
Enter	Enter
Tab	Tab
Space	Space
