7.10 The Calc Mode Line

This section is a summary of all symbols that can appear on the Calc mode line, the highlighted bar that appears under the Calc stack window (or under an editing window in Embedded Mode).

The basic mode line format is:

 
--%%-Calc: 12 Deg other modes       (Calculator)

The `%%' is the Emacs symbol for "read-only"; it shows that regular Emacs commands are not allowed to edit the stack buffer as if it were text.

The word `Calc:' changes to `CalcEmbed:' if Embedded Mode is enabled. The words after this describe the various Calc modes that are in effect.

The first mode is always the current precision, an integer. The second mode is always the angular mode, either Deg, Rad, or Hms.

Here is a complete list of the remaining symbols that can appear on the mode line:

Alg
Algebraic mode (m a; see section 4.5 Algebraic Entry).

Alg[(
Incomplete algebraic mode (C-u m a).

Alg*
Total algebraic mode (m t).

Symb

Matrix
Matrix mode (m v; see section 7.4.6 Matrix and Scalar Modes).

Matrixn
Dimensioned matrix mode (C-u n m v).

Scalar
Scalar mode (m v; see section 7.4.6 Matrix and Scalar Modes).

Polar

Wide
No line breaking (d b).

Break
Selections show deep structure (j b; see section 11.1.1 Making Selections).

Save
Record modes in `~/.emacs' (m R; see section 7.1 General Mode Commands).

Local

Sel
Top-of-stack has a selection (Embedded only; see section 11.1.1 Making Selections).

Dirty
The stack display may not be up-to-date (see section 7.7 Display Modes).

Inv

Hyp
"Hyperbolic" prefix was pressed (H).

Keep
"Keep-arguments" prefix was pressed (K).

Narrow
Stack is truncated (d t; see section 7.7.8 Truncating the Stack).

In addition, the symbols Active and ~Active can appear as minor modes on an Embedded buffer's mode line. See section 17. Embedded Mode.
