title: Keyboard/configuration shortcut to switch between tabbed windows (project/window tabs, not file tabs within a project) in Sublime Text 3
body: <p>You are now able to group separate windows/projects into one main view and switch between them by clicking the tabs. When they were separate windows, you could use 'cmd+`' to switch between them on MacOS. This no longer works in project/window tabs.</p>
  
  <p>Looking for the keybindings to set this, hopefully OS-agnostic.</p>
