Hint grid for keyboard-centric flow

[hermanhel]

Feature Description

After invoking with hint grid(perhaps with flameshot gui hint, or a custom keybinding ~f~ after flameshot gui is invoked), showing uniform grid of points on the screen each labled with letters. User could select 2 points by typing those letters to select the initial selected area(upleft and botomright point).(and perhaps use arrowkeys and shift-arrowkeys to do minor adjustments)

Reference images: (from https://stackoverflow.com/a/77623571/22281666) (in the image the hints are on link objects)

This would make full-keyboard workflow faster and much more natural with flameshot.

This is a very cool idea in concept, but I have no idea how we could implement it. We would need to run some sort of ML model or classic computer vision to identify "points of interest" to place a hotkey next to. I suspect any such algorithm would work poorly in practice.
