Each keyboard macro has an associated counter. Normally, the
macro counter is initialized to 0 when you start defining the macro,
and incremented by 1 after each insertion of the counter value;
@findex kmacro-insert-counter
@kindex C-x C-k C-i
The command @kbd{C-x C-k C-i} (@code{kmacro-insert-counter}) inserts
-the current value of the keyboard macro counter and increments the
-counter by 1. You can use a numeric prefix argument to specify a
-different increment. If you just specify a @kbd{C-u} prefix, the last
-inserted counter value is repeated and the counter is not incremented.

+increments the counter by 1. You can use a numeric prefix argument to
+specify a different increment. If you just specify a @kbd{C-u}
+prefix, then the increment is zero, so it repeats the last inserted
+counter value. For example, if you enter the following sequence while

@findex kmacro-set-counter
@kindex C-x C-k C-c
- The command @kbd{C-x C-k C-c} (@code{kmacro-set-counter}) prompts
-for the initial value of the keyboard macro counter if you use it
-before you define a keyboard macro. If you use it before executing a
-keyboard macro, it resets that macro's counter. If you use it while
-defining a keyboard macro, then the macro counter gets reset to that same
-value on each repetition of the macro. Rather than having the command
-prompt for a value, you can also specify the value with a numeric
-prefix argument. If you just specify a @kbd{C-u} prefix, the counter
-is reset to the value it had prior to the current repetition of the
-macro (undoing any increments so far in this repetition). If you just
-specify a @kbd{C-u} prefix while no macro is being defined or executed,
-then the new value of the counter is essentially unpredictable.
+ The command @kbd{C-x C-k C-c} (@code{kmacro-set-counter}) sets the
+current macro counter to the value of the numeric argument. If you use
+it inside the macro, it operates on each repetition of the macro. If
+you specify just @kbd{C-u} as the prefix, while executing the macro,
+that resets the counter to the value it had at the beginning of the
+current repetition of the macro (undoing any increments so far in this
+repetition).
@findex kmacro-add-counter
@kindex C-x C-k C-a
- The command @kbd{C-x C-k C-a} (@code{kmacro-add-counter}) prompts
-for a value to add to the macro counter. You can also specify the
-value with a numeric prefix argument. If you just specify a @kbd{C-u}
-prefix, the counter is reset to the last value inserted by any
-keyboard macro. Usually, this will only make sense if that value was
-inserted during the current macro definition or repetition.

- This command normally only makes sense while defining a keyboard macro.
-But its behavior when no keyboard macro is being defined or executed
-is predictable: it affects the counter of the head of the keyboard
-macro ring.
+ The command @kbd{C-x C-k C-a} (@code{kmacro-add-counter}) adds the
+prefix argument to the current macro counter. With just @kbd{C-u} as
+argument, it resets the counter to the last value inserted by any
+keyboard macro. (Normally, when you use this, the last insertion
+will be in the same macro and it will be the same counter.)
