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.

(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 `M-#
k' (`calc-keypad').  This means that the command is normally used by
pressing the `p' key or `M-# 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'].
