nice, thank you and one more thing, how could I have different levels of movement placed on other keys? For example, let's suppose that as it is (200 and 3) is ok, but of course it's very slow, so I would like to have the option to have another key that when pressing it, goes from 200 and 3 to 200 and 15, having this way the possibility of pressing "end" for 200 and 3 while pressing "1" goes to 200 and 15.By very little extended you mean the movement is short? try this:
The 2 lines of "sleep 200" change it to 250 or 300 on both. The smaller the number it is the faster and shorter the movement gets.
The 2 lines of "send {wheelup 3}" and "send {wheeldown 3}" change the number to 4 on both. The higher the number the bigger the scrolling/movement up or down is.
