 Restrict the actions remote control is allowed to take. This works like
 :opt:`remote_control_password`. You can specify a password and list of actions
 just as for :opt:`remote_control_password`. For example::
-
     --remote-control-password '"my passphrase" get-* set-colors'
 
 This password will be in effect for this window only.
 Note that any passwords you have defined for :opt:`remote_control_password`
 in :file:`kitty.conf` are also in effect. You can override them by using the same password here.
 You can also disable all :opt:`remote_control_password` global passwords for this window, by using::
-
     --remote-control-password '!'
 
 This option only takes effect if :option:`--allow-remote-control`
