By holding down the "meta" key (⌘ on Mac, ⊞ on Windows) and moving your cursor across the device screen, you can see the X/Y coordinates of that specific position. This is useful for figuring out the coordinates of an element that you want to click on using the Arm

API.

The coordinates are shown in the bottom left corner of the screen in two formats: Physical which is the actual pixel position on the screen and Normalized which is the position of the pixel relative to the video stream. The latter is what you should use when writing your automation scripts.
