Very weird trackpad gestures

Hi,
macOS relly lacks proper documentation. So in the trackpad commanders we have these secondary single, double and triple click, right? There is no indication as to how to perform them *as far as I know*. My obvious guess would've been that it's something to do with the force touch compatible trackpads, but no. For whatever reason, if it's a feature and not a bug (if there are users using this daily please tell us whether you discovered this yourself or in the doc?) you have to do the same thing as the regular click but maintaining two fingers on the trackpad, and then do it twice or thrice. Hope this can help unlock more gestures with the commander, you obviously have to use a modifier key otherwise it won't work, because using one hand would've been to convenient :) .
