This document provides a few tips relating to TOPS-20. For a more detailed
introduction, including command examples, see <DOCUMENTATION>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 <doc" and press ESC, it will fill in the
line as "dir <docUMENTATION>*.*.*"
^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. You can
find much more detail on using and/or worshipping emacs elsewhere.
^P/^N Previous Line / Next Line
^F/^B Forward / Backward 1 Character
^A/^E Start / End of Line
^X ^S Save
^X ^C Exit Emacs
