Logout and refresh
<Exit/> (Logout) is the menu command to cleanly log out of the current X server.
<Restart/> (Refresh) is the menu command tag which reinitializes the configuration file and updates menus and keybindings accordingly.
<Exit/> can be bound to the
Ctrl+Alt modified keys following the example syntax below:
<Key mask="CA" key="r">exec:jwm -restart</Key> <Key mask="CA" key="e">exec:jwm -exit</Key>
Reboot and shutdown
A system with systemd can be rebooted with the
Poweroff menu options.

Manual tiling support
Tiling support can be added to JWM with the Poor Man's Tiling Window Manager. Assuming
manage.py is part of the local
PATH, various tiling actions can be assigned to keys, for example:
<Key mask="H" key="Up">exec:manage.py swap</Key> <Key mask="H" key="Down">exec:manage.py cycle</Key> <Key mask="H" key="Left">exec:manage.py left</Key> <Key mask="H" key="Right">exec:manage.py right</Key>
