sxhkd [Options] [EXTRA_CONFIG ...]

sxhkd is a simple X hotkey daemon with a powerful and compact configuration syntax.

-h

Print the synopsis to standard output and exit.

-v

Print the version information to standard output and exit.

-m COUNT

Handle the first COUNT mapping notify events.

-t TIMEOUT

Timeout in seconds for the recording of chord chains.

-c CONFIG_FILE

Read the main configuration from the given file.

-r REDIR_FILE

Redirect the commands output to the given file.

-s STATUS_FIFO

Output status information to the given FIFO.

-a ABORT_KEYSYM

Name of the keysym used for aborting chord chains.

sxhkd is a daemon that listens to keyboard events and execute commands.

It reads its configuration file from $XDG_CONFIG_HOME/sxhkd/sxhkdrc by default, or from the given file if the -c option is used.

Additional configuration files can be passed as arguments.

If sxhkd receives a SIGUSR1 (resp. SIGUSR2) signal, it will reload its configuration file (resp. toggle the grabbing state of all its bindings).

The commands are executed via SHELL -c COMMAND (hence you can use environment variables).

SHELL will be the content of the first defined environment variable in the following list: SXHKD_SHELL, SHELL.

If you have a non-QWERTY keyboard or a non-standard layout configuration, you should provide a COUNT of 1 to the -m option or -1 (interpreted as infinity) if you constantly switch from one layout to the other (sxhkd ignores all mapping notify events by default because the majority of those events are pointless).

Each line of the configuration file is interpreted as so:

• If it is empty or starts with #, it is ignored.
• If it starts with a space, it is read as a command.
• Otherwise, it is read as a hotkey.

General syntax:

HOTKEY
    [;]COMMAND

HOTKEY      := CHORD_1 ; CHORD_2 ; ... ; CHORD_n
CHORD_i     := [MODIFIERS_i +] [~][@]KEYSYM_i
MODIFIERS_i := MODIFIER_i1 + MODIFIER_i2 + ... + MODIFIER_ik

The valid modifier names are: super, hyper, meta, alt, control, ctrl, shift, mode_switch, lock, mod1, mod2, mod3, mod4, mod5 and any.

The keysym names are given by the output of xev -event keyboard.

Hotkeys and commands can be spread across multiple lines by ending each partial line with a backslash character.

When multiple chords are separated by semicolons, the hotkey is a chord chain: the command will only be executed after receiving each chord of the chain in consecutive order.

The colon character can be used instead of the semicolon to indicate that the chord chain shall not be aborted when the chain tail is reached.

If a command starts with a semicolon, it will be executed synchronously, otherwise asynchronously.

The Escape key can be used to abort a chord chain.

If @ is added at the beginning of the keysym, the command will be run on key release events, otherwise on key press events.

If ~ is added at the beginning of the keysym, the captured event will be replayed for the other clients.

Pointer hotkeys can be defined by using one of the following special keysym names: button1, button2, button3, ..., button24.

The hotkey and the command may contain sequences of the form {STRING_1,...,STRING_N}.

In addition, the sequences can contain ranges of the form A-Z where A and Z are alphanumeric characters.

The underscore character represents an empty sequence element.
