track matte option seems to have disappeared and cant find it
Sorry if this is a stupid or obvious question. Usually, you hit f4 to bring up the track matte column, right? But ever since switching to MacBook 15" where the f keys are substituted by the touch bar, that short cut won't work. (even by holding function key). I also can't access it by right clicking "switch" and selecting "column," as shown on a track matte tutorial. I'm on the latest AE, by the way. Can anyone tell me how to bring up the trkmatte options?
Thanks!
