Be aware that a lot of distros will be switching from X11 to Wayland at some point in the not-too-distant future and these ancient tools will not work there.

People have tried to write equivalents (ydotool is one I'm aware of), but Wayland has intentionally been written to make doing such things difficult, for "security" reasons.

I will be grumpy until I can make my scripts work again, but that's for future me to deal with.
