Keyboard Modifier Status for XFCE is an XFCE port of the Keyboard-Modifier-Status extension for Gnome Shell.
It provides a visual indication of the modifier keys currently pressed and is mostly useful if you're using sticky keys.
In addition to the XFCE development libraries make sure xdt-csource
(XFCE >= 4.18) or exo-csource
(XFCE <4.18) is installed on your system. It's probably available as part of the package xfce4-dev-tools
or similar from your distribution's package manager.
The plugin uses the Meson Build System.
$ meson setup build
