It would be great to have arrows at top and bottom of the vertical scroll bar to look at many images in the library with control. With the draggable square it's just too coarse to allow control. (hope I'm being clear)
Assuming LR Classic, in the Grid view, if you click anywhere below the box in the vertical scroll bar you'll go to the next page of images. Click above the box and you'll go to the prior page of images. Same thing if you use the Page Up and Page Down buttons on your keyboard - one page at a time up or down. is that what you want to do or something else?
Yes, LR classic! And WOOOW! Not exactly what I was suggesting, but infinitely better than what I was aware of. What I wanted was (is) arrows at top and bottom of scroll bar like in Word and most other software that you can move by as little or much as you want. BUT I discovered in testing your method, if you have a down arrow on the lowest row, it will go down by one row so this will work for what I'm asking. Many thanks!
