List of ASCII codes
To select a character from the extended set, press the Alt key with the 
left hand, and simultaneously type the number on the numeric key pad
(not the top row numbers) with the right hand. When you release the Alt
key, the character will be displayed.
Note that characters with a value < 32 are used for special control
commands, and as such will not display like the others do.

Note: Every magnetic particle in a computer is in one of 2 states: charged
or not charged (i.e. holds a 1 or a zero). Every 8 particles (or bits) can
hold 2(to the 8th power) variations i.e. 256 different codes (or bytes).
These make up ASCII - American Standard Code for Information Interchange.
