If you purchase the ipad app VNC Viewer, by Real VNC, when you tap at the top of the screen, instead of choosing keyboard, choose mouse, then at the bottom right of the screen, you will have a left and right
mouse button you can use. By the way, if you hold the left mouse button and move your other finger, you can use the "drag and drop" or resize windows if you want.
How does Google Maps work on those devices with having a right-click feture?
