Alt-5 - Selects Command window
 Make the command window the current window.
──────────────────────────────────────────────────────────────────────────────

 You may select the command window by pressing <Alt><5>. If the Command
 window is not the current window, pressing <Alt><5> will make it the current
 window, if you have this option set from the options menu, otherwise this
 window will not become the current window

 You may like to know that if you simply press nearly any key on the
 keyboard, the command window will become the current window and assume that
 you are typing a command.
