Thank you for your reply!

1. From the issue I pulled this feature from, the main use case for this is with NVDA's viewers (speech, braille, log, etc) so you can get a feeling of where on screen they are.

2. Currently, using this shortcut, there is no feedback whatsoever to the user. In the debug log, all that is tracked is the input of an arrow key.

The implementation I am looking at trying will behave similarly to the user feedback when moving an image/textbox within powerpoint when NVDA is active. That is, when the window is moved, the position would be read as "X points from the left screen edge", "X points from the right screen edge" when moving horizontally, "X points from the top screen edge", "X points from the bottom screen edge" when moving vertically. NVDAObjects (like the Window class) already have the _get_locationText that returns:
"Object edges positioned {left:.1f} percent from left edge of screen, "
"{top:.1f} percent from top edge of screen, "
"width is {width:.1f} percent of screen, "
"height is {height:.1f} percent of screen",

1. I have tested this suggestion with Windows narrator and no user feedback options exist for this interaction. If there is anything additional you would like me to clarify, please let me know.
