If set to false, you can scroll to cycle through workspaces without mouse warping being enabled. If set to true this behaviour is disabled.
*window-rewrite*: ++
typeof: object ++
Regex rules to map window class to an icon or preferred method of representation for a workspace's window.
Keys are the rules, while the values are the methods of representation.
Rules may specify `class<...>`, `title<...>`, or both in order to fine-tune the matching.

The default method of representation for a workspace's window. This will be used for windows whose classes do not match any of the rules in *window-rewrite*.
