As I am not familiar with AutoKey, could you please tell me what V2 code would it be to simply scroll up in case the F14 key is triggered, and scoll down in case the F13 key is triggered (yes, I have those two...) ? Nothing fancy about the scrolling speed or so, I only need it as simple as that.

This is to use something else than my mouse wheel that sometimes "stutters", but most of all, to make better use of the wheel knob from the Ulanzi D100H controler which triggers those F13 and F14 as virtual mouse wheel. Very good, efficient and quick to zoom in and out in apps that do not partner with Ulanzi for plugins, but I would like it to also scroll up and down in normal windows. Quick scrolling up and down would be practical in my photo editing software to quickly navigate in the lateral settings modules on each side of the central picture preview (on which the "scrolling" zooms and dezooms).

I already have those two lines below, but curiously this does not scroll, this does only zooming or dezooming in some programs like photo editing or so, no scrolling up or down on Windows or internet pages.

*F14::SendEvent("+{WheelUp}")

*F13::SendEvent("+{WheelDown}")
