There are a few ways to make a timeline in Photoshop. One way is to use the timeline tools in the Tools palette. The other way is to use the Timeline tool in the Timeline panel of the Edit menu. The first way is more common and works best when you want to create a timeline that spans several pages or even entire files. To create a timeline, click on one of the points on the timeline and then drag it left or right until you’ve created a new line. The second way works best when you want to create a single, continuous timeline. To do this, click on one of the points on the timeline and then drag it up or down until you’ve created a new line.
