RUBOUTKey
The RUB OUT key generates an octal code
377 each time it is pressed. For example, by
backspacing a paper tape and punching RUB
OUT over an error, the error is converted to octal
code 377 and will be ignored upon subsequent
reading.
REPTKey
The REPT (REPEAT) key, when pressed
simultaneously with another key, causes the
normal action of the other key to be repeated as
long as the two keys are pressed.
ALTMODE Key
The ALT MODE key, when pressed, produces
an octal code of 375. When ALT MODE is
pressed simultaneously with the CTRL key, an
octal code of 275 is produced.
