I'm working on a sketch and typed "pulse" and was about to continue type something else to make a new function, but "pulse" turned orange, meaning it's some kind of keyword. Googleing the word I get overloaded with stuff, mostly about pulseIn().
I tried the language reference here:
and it too only found pulseIn().
Where can I find out what "pulse" means to Arduino? It might do what i am trying to do and therefore I can use it rather than reinvent the wheel.
I also tried F1 while the word was selected.
