Show Me The Key displays your keystrokes on screen for screencasts, presentations and tutorials. It reads events through libinput, so it works on both Wayland and X11 (unlike screenkey, which is X11-only).
Because reading /dev/input requires privilege, this snap is split into a root backend that runs as a system daemon and an unprivileged GTK frontend. Two manual steps are required after install:
# sensitive: grants the snap the ability to read all input events
sudo snap connect showmethekey:raw-input
sudo snap connect showmethekey:hardware-observe
On a Wayland session the floating key window can't place itself, so right-click its title bar and enable "Always on Top" and "Always on Visible Workspace".

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
On Arch Linux, snap can be installed from the Arch User Repository (AUR). The manual build process is the Arch-supported install method for AUR packages, and you’ll need the prerequisites installed before you can install any AUR package. You can then install snap with the following:
git clone https://aur.archlinux.org/snapd.git
cd snapd
makepkg -si
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
If AppArmor is enabled in your system, enable the service which loads AppArmor profiles for snaps:
sudo systemctl enable --now snapd.apparmor.service
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install Show Me The Key, simply use the following command:
sudo snap install showmethekey --edge
Browse and find snaps from the convenience of your desktop using the snap store snap.
