Installation

Install sxhkd or sxhkd-gitAUR.

Configuration

sxhkd defaults to $XDG_CONFIG_HOME/sxhkd/sxhkdrc for its configuration file. An alternate configuration file can be specified with the -c option.

Each line of the configuration file is interpreted as so:

  • If it starts with #, it is ignored.
  • If it starts with one or more white space commands, it is read as a command.
  • Otherwise, it is parsed as a hotkey: each key name is separated by spaces and/or characters.

General syntax:

[MODIFIER + ]*[@|!]KEYSYM
    COMMAND

Where is one of the following names: , , , alt, , , , mode_switch, , , , , , mod5. 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 command will be run on motion notify events and must contain two integer conversion specifications which will be replaced by the x and y coordinates of the pointer relative to the root window referential (the only valid button keysyms for this type of hotkeys are: , ..., ). The names are those your will get from xev.

Mouse hotkeys can be defined by using one of the following special keysym names: , , , ..., . The hotkey can contain a sequence of the form {STRING_1,…,}, in which case, the command must also contain a sequence with N elements: the pairing of the two sequences generates N hotkeys. If the command includes curly braces (, ) eg. , escape them with backslash eg. . In addition, the sequences can contain ranges of the form A-Z where A and Z are alphanumeric characters.

What is actually executed is , which means you can use environment variables in . will be the content of the first defined environment variable in the following list: SXHKD_SHELL, . If sxhkd receives a signal, it will reload its configuration file.

Usage

After configuring it, you may wish to setup sxhkd to autostart. An example systemd service file is found here. This approach requires configuring Xorg as a systemd user service.

Alternatively, if your desktop environment supports the Desktop Application Autostart Specification you can also have it start sxhkd by creating an file in the appropiate directory:

Example

Then restart the user unit .

gollark: Tesla more so. They have some "extra acceleration" purchase for old cars which seems to just change some software settings and costs $2000.
gollark: They do seem to have not very user controllable software.
gollark: Wouldn't you expect any sort of big advantages Tesla has to already be reflected in the price of its shares?
gollark: They're ahead of humans at *some* things, and a lot behind on others.
gollark: For chess.
