I have a touchscreen on an old notepad on which I used to use BIAB.
AFAICS it operated as Jim described ... as a mouse.
I'm not sure I tried anything else. Mostly I used keyboard and mouse anyway.

I do use a large touchscreen on a Linux machine to control DAWs and my mixer, but there I have multiple desktops with different sets of software on each.
