Looking at the squeakvm source, there was a primitive for setting

the cursor position:

InputSensor>> cursorPoint: aPoint
    "Set aPoint to be the current cursor location."

    ^self primCursorLocPut: aPoint

And

InputSensor>>primCursorLocPut: aPoint
    "If the primitive fails, try again with a rounded point."

    <primitive: 91>
    ^ self primCursorLocPutAgain: aPoint rounded

Curiosly nowadays the primitive 91 is used for testDisplayDepth,

so printing

InputSensor default cursorPoint:(100@100)
fails (returns self)
and
InputSensor default cursorPoint:31

or

InputSensor default cursorPoint:32

results in false or true

Pharo removed the #cursorPoint: selector.

You can have a look at it on

we should continue to work on it. Fernando is using it since quite a moment :)
