title: alt-tab like functionality when using terminal?
body: <p>When working in GUI we do alt-tab (or cmd-tab in mac) to switch between multiple programs, for example I am writing a text file in a text editor and then I do alt-tab to switch to already running browser to google up something then I alt-tab again to come back to keep editing.</p>
  
  <p>How do you perform such "switch between" programs in command line interface - for example working with a ssh command line shell?</p>
  
  <p>EDIT: I forgot to mention it, I am using ssh to connect to my university's server, and they don't have screen &amp; tmux installed, and my account have no right to install any new apps... Is there any built-in functionality to perform this task, or any work around? For exmaple can I "minimize" running proggram and come back to regular shell interface, do some work, then display the "minimized" process again?</p>
