Visidata: How can I customize the mouse scrollwheel events to reverse the motion?

[deinspanjer]

I'm using a MacBook, and I'm set in my ways, so the first thing I do is change the touchpad configuration to not be "Normal". This means if I swipe downward, the window scrolls down, and if I swipe upward, it scrolls up.

Unfortunately, OSX ties the scroll direction together for both the touchpad and the mousewheel, so that means when I swipe upward, Python receives this as a BUTTON4_PRESSED event, and downward is a BUTTON2_PRESSED.

I'd like to reverse these, but I haven't found the right part of the code yet to hopefully find an example of a Command() I can override in .visidatarc.

Hi @deinspanjer! It's even easier than overriding the command. You can just set the scroll_incr option, which by default is 3, to its inverse (-3), in your .visidatarc:

options.scroll_incr = -3

That is a great little hack. Thanks Saul. I am really really loving visidata.
