imwheel 1.0.0pre12-15build1 (s390x binary) in ubuntu lunar

 Many mice have side or "thumb" buttons that see limited use in Linux,
 as well as a wheel that is not used by many older applications.
 .
 IMWheel supports these non-standard buttons and/or wheel operations
 by allowing the user to map their input to specific key combinations
 depending on the application in use.
