# Scroll the mouse wheel at a position on the host computer

`POST /computer/scroll`

Scroll vertically and/or horizontally at the given coordinates, optionally while holding modifier keys.
The scroll amounts are in logical ticks (not pixels) and application behavior may vary; tuning may be required.
When both horizontal and vertical deltas are provided, the server applies them sequentially (vertical then horizontal)
and batches wheel events using `xdotool click --repeat N --delay 0 <button>`.
