It is surprising to me how this would not be one of the first things to learn in Pd.

Speaking only for myself, there's a gap between the principle and understanding the application of the principle. Or, you have to get some distance into patching before you really grasp why [f] is important. Just like there are points of confusion in learning SuperCollider that I forgot about long ago.

I do agree there's no need for a PR, but I think the help should illustrate. I could PR something later.
