 	Binds _key combo_ to execute the sway command _command_ when pressed. You
 	may use XKB key names here (*xev*(1) is a good tool for discovering these).
 	With the flag _--release_, the command is executed when the key combo is
 	released. Unless the flag _--locked_ is set, the command will not be run
 	when a screen locking program is active. If _input-device_ is given, the
 	binding will only be executed for that input device and will be executed
