Change keyboard shortcut (.emacs): Change shell keyboard shortcut from f5 to f9. The command use will also change from shell to term since shell is the oldest of the shells (shell, eshell, and term). eshell was previously used but it simply mimicks a shell while term actually uses what the current terminal is capable of.
Update keyboard shortcut (README.md): Change shell keyboard shortcut from <f5> to <f9>. This is to reflect the keybinding update on .emacs file.
