Hello! I'm a relatively new user to plan 9, and I am studying it as part of an elective unit at university for free and open source software development. So far the experience is interesting and I am using a plan9 port to test out the features of plan9. I have a question about keyboard and mouse interaction in the OS that relates to fast keys available for the windows. Do any exist for use of say windows switching, closing or any other operations for menus within plan 9?
