- (code page 437) activated.
- Ctrl-Alt-F2* By pressing the keys Ctrl-Alt-F2, the keyboard definition for

- work on your system, you can assign it to do this, with
-
- PROMPT $e[08;0;75p
-
- See the "SUMMARY KEYBOARD ASSIGNMENT_OF_KEYS" topic for
- details. Most separately purchased programs will probably
- ignore the assignment.
- Ctrl-NumLock Pressing the Ctrl-Numlock key will "freeze" (stop whatever is
- being displayed on the screen) so that you can examine it.
- Pressing any other key will then unfreeze the screen.
- Ctrl-P See Ctrl-PrtSc.
- Ctrl-PrtSc Ctrl-PrtSc is used to turn on or turn off the "echoing" of
- everything that is displayed on the screen to the printer.
- Ctrl-S Ctrl-S is another way to "freeze" the screen. It doesn't
- always work. Ctrl-NumLock is more reliable.
- Ctrl-U On some DOS systems, the Ctrl-U key works like Esc or Escape.
- See the "SUMMARY COMMAND_EDITING" topic for additional
- information about command line editing. If Ctrl-U does
- not work on your system, you can assign it to do this, with
-

-

- Ctrl-W On some DOS systems, the Ctrl-W key is a way to throw away the
- last word that had been entered as part of a command line. It
- backs up to the previous special character. See the "SUMMARY
- COMMAND_EDITING" topic for additional information about
- command line editing.
- Ctrl-Z Ctrl-Z is used to indicate that the end of input from the
- keyboard has occurred. When the Ctrl-Z key is used this way, it
- should be entered on a line by itself. Then the Return, Enter,
- or <──┘ key should be pressed. Frequently the F6 function key
- will do the same thing as the Ctrl-Z key.
-
- The character entered by the Ctrl-Z key is used in DOS files
- to indicate an end-of-file. DOS commands (including TYPE and
- COPY /A) and some separately purchased programs, like editors,
- will stop processing the data in the file when they encounter
- a Ctrl-Z character.
