I prefer to use keyboard bindings when I can. One binding I haven’t been able to figure out is closing the REPL pane (I think it is called a pane but I could be wrong). I can do it with the mouse by clicking on the down arrow in the semicircle above the name REPL. Once it is closed you can open it again with -J -O.
Similarly -9 opens the git pane to the right but I can only close it by hovering around the boundary until the right-arrow in a semi-circle appears.
Can someone help me expand my Atom knowledge?
