Can't seem to find documentation on mouse_click and mouse_drag

I am gonna try and make one of the best OSes ever but I can't find any documentation on the mouse functions. I'd appreciate some help please. Thanks in advance

You want the os.pullEvent() "mouse_click".

In the paint program there is a mouse_drag event. Where is the information about that?

You can try asking the program creator about it.

Or you can use a repeat t_event = {os.pullEvent()} print(textutils.serialize(t_event)) until t_event[2] == "X" to check out what kinds of events you can see. Play around, just don't press Shift+X till you're done.
