This is down to the OS, really. On macOS, I scroll X & Y with my touchpad just fine.

The Pd GUI uses the default Tk scrolling mechanism, if you want to tinker: https://www.tcl.tk/man/tcl8.5/TkCmd/scrollbar.htm

Oh yeah, that seems to work in Linux too!

Actually, trying it in Windows now, I find that horizontal scrolling does work even without the Shift key. But it's extremely slow, and you can only scroll X or Y independently, not both at the same time.

It doesn't seem to be possible in any OS to scroll X and Y at the same time. Would other people find this useful? Perhaps there could be a startup flag that determines whether to allow dual-axis scrolling or whether to keep the current behavior.
