Perspective - touchscreen - how many touches

I'm on 8.1.41

Is there a way to get the number of touched points on the screen for a click event?

The onClick event should give you a list of parameters/properties that are available. It think there's one called "clickCount" - at least there is in Vision.

Not available in Perspective

What is the reason/use case? Perhaps this is an XP problem and there is a better solution than what you might think.

I want to implement different action according to number of touches

First case, want to navigate in new tab when 2 touches else in same tab

I really don't have much to offer, but I will say your implementation seems weird and unintuitive to me, just my opinion of course.

Maybe make a template with 2 buttons with distinct icons. @luc.martin is correct that it's fairly unintuitive
