If you just press 'Return' when it starts up, with 'Basic Screen
Operations' highlighted, you'll get some help.

If you look long enough, you'll find a page named 'Using Keys and Key
Sequences in the InfoExplorer ASCII Interface'.  It describes the key
sequences and actions.  Here are a few to get you started.

Keys       Action

Ctrl-W     Moves between the Navigation screen and the Reading screen.
If the Navigation screen is displayed, you can press Ctrl-W to display
the Reading screen.  If the Reading screen is displayed, you can press
Ctrl-W to display the Navigation screen.

Ctrl-O     Makes the menu bar active or inactive.  If your text cursor is
located in the text area of the screen, you can press Ctrl-O to make the
menu bar active.  If the menu bar is already active, you can press
Ctrl-O to make it inactive, which moves the text cursor to the text area.

Tab     Moves to the next menu bar option in the menu bar.  If a pull-down
menu is not displayed and you press the Right Arrow key, the next menu
bar option is displayed in reverse video.
