Problem: I'm frustated to try to move my mouse cursor pixel by pyxel on X AND Y axis

Solution: like the ShareX application, it would be nice to adjust position with arrows keys (with the zoom activated). That way, I'm sur to only capture pixels I want on my screenshot.

Details: when ksnip is ready to capture an area, use mouse to mouse reticule roughly then use arrows keys for pixel by pixel move, then click and keep mouse button down for second point of area with arrows keys to adjust again pixel by pixel. Release button for accepting the area.
Thanks
