test:mouse-click

• (test:mouse-click button x y modifiers) -> void
      button : (union 'left 'middle 'right)
      x : inexact
      y : inexact
      modifiers = null : (listof (union 'alt 'control 'meta 'shift 'noalt 'nocontrol 'nometa 'noshift))

  Simulates a mouse click at the coordinate: (x,y) in the currently focused window<%>, assuming that it supports the on-event method. Use test:button-push to click on a button.

  On the Macintosh, 'right corresponds to holding down the command modifier key while clicking and 'middle cannot be generated.

  Under Windows, 'middle can only be generated if the user has a three button mouse.

  The modifiers later in the list modifiers take precedence over ones that appear earlier.
