In the table below:

F is a Final character in
an Escape sequence (F from 48 to 126 in the ASCII table)
a control sequence (F from 64 to 126).

Fe is a Final character in ASCII range 64 to 95.

Gs is a graphic character appearing in strings (Gs ranges from
32 to 126) in the ASCII table.

C0 is the set of 7-bit ASCII control characters from 0 to 31.

C1 the set of control characters available only in 8-bit systems.

Ce is a control represented as a single bit combination in the C1 set
of controls in an 8-bit character set.

I is an Intermediate character from 32 to 47 (inclusive) in the
ASCII table.

P is a parameter character from 48 to 63 (inclusive) in the ASCII
table.

Pn is a numeric parameter in a control sequence, a string of zero or
more characters ranging from 48 to 57 in the ASCII table.
Numeric parameters must be in decimal radix.

Ps is a variable number of selective parameters in a control sequence
with each selective parameter separated from the other by the code
59 (which usually represents a semicolon); Ps ranges from
48 to 57 and 59.

IBM PC Keyboard Reassignment:

Keyboard reassignment uses an undefined ANSI X3.64-1979 code sequence
to define a character or set of characters send by the console whenever
a given key is pressed on an IBM PC compatible. The control sequence
is:

ESC [ Pn ; Pn ; ... Pn p

or

ESC [ "string" ; p

The first ASCII code in the sequence defines which code is being mapped.
If the first code is 0 (nul), then the second code is the extended
IBM keycode. The remaining numbers define the sequence of ASCII codes
generated when this key is intercepted, or the string (enclosed in
quotes) to be generated. For example:

ESC [65;81p A becomes Q
ESC [0;68;"dir";13p F10 generates dir followed by a CR.
