+		Returns a Dictionary with the last known position of the
+		mouse.  This can be used in a mapping for a mouse click or in
+		a filter of a popup window.  The items are:
+			screenrow	screen row
+			screencol	screen column
+			winid		Window ID of the click
+			winrow		row inside "winid"
+			wincol		column inside "winid"
+			line		text line inside "winid"
+			column		text column inside "winid"
+		All numbers are 1-based.
+
+		If not over a window, e.g. when in the command line, then only
+		"screenrow" and "screencol" are valid, the others are zero.
+
+		When on the status line below a window or the vertical
+		separater right of a window, the "line" and "column" values
+		are zero.
+
+		When the position is after the text then "column" is the
+		length of the text in bytes.
+
+		If the mouse is over a popup window then that window is used.
+
+
+		When using |getchar()| the Vim variables |v:mouse_lnum|,
+		|v:mouse_col| and |v:mouse_winid| also provide these values.
