On a laptop, the Illustrator screen is very detailed. The screenshot shows how, when object>transform has been selected, it is necessary to hold down the mouse button and slide the mouse so that the cursor is guided down a very narrow blue track. If you stray off after careful steering to almost the end, you have to start again. Why not make the blue track much wider, so that you do not have to exert such close manual control? You could , for example, make the track expand in width as it extends from the start box to the end menu.
