• I've have putting guide lines in my sheet and I want to make Selection for the some of the rectangles that form from these line.......... Is it possible to make selection by using the guides?? I can only select using layers or paths

• Answer:

  Nope, you cannot. The best thing to do is make a selection with the marquee tool and save the selection. First, make a selection in your photo. Next, Choose Select > Save Selection. In the Save Selection dialog box, choose New from the Selection pop‑up menu. Enter a name for the selection in the Name box, and then click OK. To load the selection, choose Select > Load Selection, choose the saved selection from the Selection menu, and then click OK. To delete a selection, choose Select > Delete Selection, choose a saved selection from the Selection menu, and then click OK.
