STRICTMAPPER
mapper
Wraps a mapper or a macro in such a way that MAP will only call it if the number of ticks in the window is in the specified range.
Since 2.1 STRICTMAPPER can also take a timespan definition by inputing negative numbers. Number of ticks and timespan can also be mixed to specify, for instance, more than 2 points but less than 5 seconds.
Prior to 2.8 STRICTMAPPER could only wrap a mapper, now it can also wrap a macro if this macro is expected to be used as a mapper.
