Character Meaning
CTRL-P Echoes all console activity to the printer. The first time you type
CTRL-P, CP/M 3 rings a bell at your console. You can use CTRL-
P after you halt scrolling with CTRL-S. A second CTRL-P ends
printer echo; no bell rings. CTRL-P has no effect if your system
does not include a printer.
CTRL-R Retypes the command line. Places a # at the current cursor location,
moves the cursor to the next line, and retypes any partial
command you typed so far.
CTRL-S Stops screen scrolling. If a display scrolls by too fast for you to
read it, type CTRL-S. CTRL-Q restarts screen scrolling.
CTRL-U Discards all the characters in the command line, places a # at the
current cursor position, and moves the cursor to the next line.
However, you can use a CTRL-W to recall any characters that
were to the left of the cursor when you pressed CTRL-U.
CTRL-W Recalls and displays previously entered command line both at the
operating system level and in executing programs, if the CTRL-
W is the first character entered after the prompt. CTRL-J, CTRL-
M, CTRL-UL, and RETURN define the command line you can
recall. If the command line contains characters, CTRL-W moves
the cursor to the end of the command line. If you press RETURN,
CP/M 3 executes the recalled command.
CTRL-X Discards all the characters left of the cursor and moves the cursor
to the beginning of the current line. CTRL-X saves any characters
right of the cursor.
