-mouse*(self: Fenster): tuple[x, y, click: int]
+mouse*(self: Fenster): tuple[x, y: int, click: array[5, int], hold: array[3, int]]
 modkey*(self: Fenster): int
 ```
 keys = Array of key states. Index corresponds to ASCII value (0-255), but arrows are 17..20.  
-mouse = Get mouse position (x, y) and click state.  
+mouse = Get mouse position (x, y), clicked (left, right, middle, scroll up, scroll down) and holding buttons (left, right, middle)  
 modkey = 4 bits mask, ctrl=1, shift=2, alt=4, meta=8
