10/29   Is there such a command in emacs where I can say "mark this point
        so I can roam around and then jump back immediately?"  -learning
        \_ Ctrl-SPACE to mark, Ctrl-X Ctrl-X to jump back.
        \_ Ctrl-SPACE to mark, Ctrl-X Ctrl-X to jump back.  You can do Ctrl-X
           Ctrl-X repeatedly to jump back and forth.
           \_ Thank emacs guru!!!
           \_ Is there a way to avoid the annoying highlighting?
              \- i am not sure exactly what you are seeing, but you might see
                 if the issue is the "transient-mark-mode" setting.
              \_ What type of file are you looking at (.cpp? .html? ...)  What
                 is emacs highlighting in that file?
