title: pyautogui notes 001
tags: python gui

I found out about this recently (kudos to [ChatGPT](https://chatgpt.com/) for knowing about it).
It makes gui automation very easy, it appears. I'd been fudging around with things like xdotool
before.

## Examples
Trivial mouse scroll wheel.
```
import pyautogui
import time
for i in range(5):
  print(i)
  time.sleep(1)
pyautogui.scroll(-10)
```
I was thinking about using the 8 knobs on a Novation Nocturn, sent via OSC, to generate
mouse scroll signals with various modifiers. For Control, Shift, Alt, there are eight
possible modifier states, and 8 knobs. Then the 16 buttons can function as macros.

The sender app needs to know none of this (so the hedgehog code is already fine).
I don't even need the paging code. But it makes sense to put this on e.g. page 16
and use the same hedgehog setup as before (that is, forward everything else to Reaper,
but page 16 we synthesise mousewheel and key combos).

That's the thinking that led me to this.
