Executing Macros With Variations

   You can use `C-x q' (`kbd-macro-query'), to get an effect similar to
that of `query-replace'.  The macro asks you  each time whether to make
a change.  When you are defining the macro, type `C-x q' at the point
where you want the query to occur.  During macro definition, the `C-x
q' does nothing, but when you invoke the macro, `C-x q' reads a
character from the terminal to decide whether to continue.

   The special answers to a `C-x q' query are SPC, DEL, `C-d', `C-l',
and `C-r'.  Any other character terminates execution of the keyboard
macro and is then read as a command.  SPC means to continue.  DEL means
to skip the remainder of this repetition of the macro, starting again
from the beginning in the next repetition.  `C-d' means to skip the
remainder of this repetition and cancel further repetition.  `C-l'
redraws the screen and asks you again for a character to specify what
to do.  `C-r' enters a recursive editing level, in which you can
perform editing that is not part of the macro.  When you exit the
recursive edit using `C-M-c', you are asked again how to continue with
the keyboard macro.  If you type a SPC at this time, the rest of the
macro definition is executed.  It is up to you to leave point and the
text in a state such that the rest of the macro will do what you want.

   `C-u C-x q', which is `C-x q' with a numeric argument, performs a
different function.  It enters a recursive edit reading input from the
keyboard, both when you type it during the definition of the macro and
when it is executed from the macro.  During definition, the editing you
do inside the recursive edit does not become part of the macro.  During
macro execution, the recursive edit gives you a chance to do some
particularized editing.  Note: Recursive Edit.
