Toggling between frames on a video layer
I've been able to toggle between frames within a video layer on the timeline by using the left and right arrows previously. However, the machine I am currently working on is not allowing this. The left and right arrows are completely unresponsive and I have to use the header to scrub between frames.
I'm not sure if this is a bug or something that can be solved by simply changing some settings. Any thoughts/solutions are appreciated.
Thanks in advance!
