I am trying to add captions to a video. In the captions area the letters turn red where the split will occur and one can click on the "Split" arrow on the left and it will split the caption at the point where the text turns red. I know I can't split the text after the point where it turns red, but I'd like to split the caption text before where it turns red because that is a more natural split. But I can't find any way to split the caption other than clicking on the "split" button and splitting it at the wrong place. Is there some way to split the caption at an earlier point? This is a pretty obvious need and I'm disappointed that there isn't an obvious way to do this that I can see.
