KeyboardStack overlays a grid on the screen and lets you reach any pixel by typing a row and a column, keeping navigation on the keyboard instead of the trackpad.

Grid Mode is free forever: press ^H, type a row and a column in either order, then click with Return, right-click with Option+Return or command-click with Command+Return.
Premium is a $29.99 one-time licence for 3 Macs, and adds Mission Control hints (^I), quick hints (^K), keyboard scrolling (^J) and HJKL cursor movement (^U).
Multi-display support cycles screens with Tab, so the grid follows the pointer across every connected monitor without switching tools.

Apple-notarised and built for macOS 27 or later; the Black Friday price is applied at checkout with no code to enter.
