Keystrokes are not visible when another app is in fullscreen mode#

You are using another app in full-screen mode, but Keystroke Pro does not display keystrokes.

Keystroke overlays can’t be displayed when you present a window in full-screen mode on macOS. This is a technical limitation of macOS itself: in full-screen mode, macOS hides all other apps and windows, which unfortunately includes Keystroke Pro (the keystroke overlays are technically a window itself).

Instead, you could simply scale the desired window to the full size of the screen. This also has the advantage of keeping the menu bar at the top of the screen permanently visible.
