USER TIPS FOR USING TOPS-20 This document provides a few tips relating to TOPS-20. For a more detailed introduction, including command examples, see INTRO1.TXT SPECIAL KEYS ? Key The ? key may be pressed almost anywhere. It will often give you hints about what the program expects int he way of input. This is a substitute for -h or /h type functionality in many cases. You can use it most any time you're expected to provide input, and it will return you to the input without the need to backspace. ESC Key ESC is used for command and filename completion. As an example, if you start typing "dir" and press ESC, you will get "dirECTORY (OF FILES)" if you press ESC again, it will fill in "*.*.*" As another example, if you type "dir *.*.*" ^C Control-C is used to break out of almost anything, returning to EXEC ^F Control-F works the way ESC does for filename and command completion ^W/^U Erase word, erase line, at the command line. ^T Use almost any time to get "session status" including system load and your running program. Does not interrupt your running program. ESSENTIAL EMACS (EDIT) KEYS These are for emergency use, in case you're a novice emacs user like me.
