added to the end of the
print queue.
2. (programming)
A data structure, the central node of a collection of

downstream messages.
quick reference keys --
Keystrokes that provide a quick way to perform a number of
useful functions: get help, exit applications,
display point-and-pick lists, search for an entry
in a point-and-pick list, and display a calendar month.

function keys.
quoting --
A mechanism that is used to control the substitution of special
characters. Special characters
enclosed in single quotes are not replaced, but
remain embedded in the text when the quotes are stripped off.
Double quotes are used to prevent the expansion of all special
characters except ``$'', ``\'' and ```''.
