Deleting points in a mask

[#1]

So I've read that to delete a mask point you just press control and click on the point. This is not working for me. What should I be doing? Can't seem to find anything online other than the option above. Thanks.

I'm replicating what you say and pressing Cmd on Mac, which is equivalent to Ctrl on Windows, works for me. Try to select the mask from the Effect Controls panel while you have the clip selected in the timeline and you get closer to the point, press Ctrl and the pen should appear with the minus (-). Look at my screenshot.
