+The SCREEN() and SCREENVISIBLE() functions return the position or size of a screen.  SCREENVISIBLE() refers to the visible section of the screen, excluding the menu bar and the dock.
-    SCREEN( index, coordinate, percentage )
-The SCREEN *index* can be 0 for the main screen, and then 1 through n are the screens in orientation order from left to right (and top down for screens at the same position). The index can also be one of:
+The SCREENINDEX() function (v10.0+) returns the actual index of the specified screen, counting from left to right.

+SCREEN( index [number OR name], coordinate )

+SCREEN( index [number OR name], coordinate, percentage )
-* Internal - the left most screen that is an internal screen (typically on a laptop).
+```
-* External - the left most screen that is not an internal screen.
-* Mouse - the left most screen containing the mouse.
-* Front - the left most screen containing (the most of) the front window.
-* Back - the left most screen not containing (the most of) the front window.
-* Back2 - the second left most screen not containing (the most of) the front window.

+The //Main// screen is set by your macOS System Preferences.
+The other screens (monitors) are referenced positionally from the left most screen, which may or may not, be the //Main// screen.

-The optional SCREEN *percentage* parameter specifies a percentage of the width or height to offset by. Offsets are always to the right and down, but negative offsets are allowed.
+The optional SCREEN //percentage// parameter specifies a percentage of the width or height to offset by. Offsets are always to the right and down, but negative offsets are allowed.
-For example SCREEN(Internal,Left,10%) would be the coordinate of left edge of the internal screen plus 10% of the width of the internal screen. SCREEN(Front,Right,-10%) would be the coordinate of the right edge of the external screen minus 10% of the width of the external screen.

 SCREEN sizes and positions are in //nominal resolution pixels// (so a retina screen will typically have half as many nominal resolution pixels as raw pixels).
-Coordinates are in absolute coordinates (relative to the top left corner of the main screen).
