Mouse buttons use keysyms of the form 'mouseup_#' or 'mousedown_#', where # is a button number. Ren'Py assumes a five button mouse, where buttons 1, 2, and 3 are the left, middle, and right buttons, while buttons 4 and 5 are generated by scrolling the wheel up and down. For example, "mousedown_1" is generally a press of the left mouse button, "mouseup_1" is a release of that button, and "mousedown_4" is a turn of the scroll wheel to the top.
