1.3 Notations Used in This Manual
=================================
This section describes the various notations that are used throughout
the Calc manual.
In keystroke sequences, uppercase letters mean you must hold down the
shift key while typing the letter. Keys pressed with Control held down
are shown as ‘C-x’. Keys pressed with Meta held down are shown as
‘M-x’. Other notations are <RET> for the Return key, <SPC> for the
space bar, <TAB> for the Tab key, <DEL> for the Delete key, and <LFD>
for the Line-Feed key. The <DEL> key is called Backspace on some
keyboards, it is whatever key you would use to correct a simple typing
error when regularly using Emacs.
(If you don’t have the <LFD> or <TAB> keys on your keyboard, the
‘C-j’ and ‘C-i’ keys are equivalent to them, respectively. If you don’t
have a Meta key, look for Alt or Extend Char. You can also press <ESC>
or ‘C-[’ first to get the same effect, so that ‘M-x’, ‘<ESC> x’, and
‘C-[ x’ are all equivalent.)
Sometimes the <RET> key is not shown when it is “obvious” that you
must press <RET> to proceed. For example, the <RET> is usually omitted
in key sequences like ‘M-x calc-keypad <RET>’.
Commands are generally shown like this: ‘p’ (‘calc-precision’) or
‘C-x * k’ (‘calc-keypad’). This means that the command is normally used
by pressing the ‘p’ key or ‘C-x * k’ key sequence, but it also has the
full-name equivalent shown, e.g., ‘M-x calc-precision’.
Commands that correspond to functions in algebraic notation are
written: ‘C’ (‘calc-cos’) [‘cos’]. This means the ‘C’ key is equivalent
to ‘M-x calc-cos’, and that the corresponding function in an
algebraic-style formula would be ‘cos(X)’.
A few commands don’t have key equivalents: ‘calc-sincos’ [‘sincos’].
