Description
We should be able to focus on the current view, for example, I have a splitview and am editing one file, I want to focus on that file and hide everything else (even the various sidebars etc..) I should have a way to do that with one key binding. Then if I want to go back to previous view I should re enter the same binding an be back in the previous view.
For vi the key should be <ctr>
