If
you wondered about the control characters, here is the meaning of some
of them on the console (Source: man console_codes). Each line
below gives the code mnemonics, its ASCII decimal number, the key combination
to produce the code on the console, and a short description:
BEL (7, <Ctrl>G) bell (=alarm, beep).
BS (8, <Ctrl>H) backspaces one column (but not past the beginning
of the line).
HT (9, <Ctrl>I) horizonal tab, goes to the next tab stop or
to the end of the line if there is no earlier tab stop.
LF (10, <Ctrl>J), VT (11, <Ctrl>K) and FF (12, <Ctrl>L)
all three give a linefeed.
CR (13, <Ctrl>M) gives a carriage return.
SO (14, <Ctrl>N) activates the G1 character set, and if LF/NL (new
line mode) is set also a carriage return.
SI (15, <Ctrl>O) activates the G0 character set.
CAN (24, <Ctrl>X) and SUB (26, <Ctrl>Z) interrupt escape sequences.
ESC (27, <Ctrl>[) starts an escape sequence.
DEL (127) is ignored.
CSI (155) control sequence introducer.
