GNU Emacs Calc 2.02 Manual
18.2.5 Queries in Keyboard Macros
The Z = (calc-kbd-report) command displays an informative
message including the value on the top of the stack. You are prompted
to enter a string. That string, along with the top-of-stack value,
is displayed unless m w (calc-working) has been used
to turn such messages off.
The Z # (calc-kbd-query) command displays a prompt message
(which you enter during macro definition), then does an algebraic entry
which takes its input from the keyboard, even during macro execution.
This command allows your keyboard macros to accept numbers or formulas
as interactive input. All the normal conventions of algebraic input,
including the use of $ characters, are supported.
See section `Kbd Macro Query' in the Emacs Manual, for a description of
C-x q (kbd-macro-query), the standard Emacs way to accept
keyboard input during a keyboard macro. In particular, you can use
C-x q to enter a recursive edit, which allows the user to perform
any Calculator operations interactively before pressing C-M-c to
return control to the keyboard macro.
