Version: 'master' (for testing) key-mon. Key-mon has more features that showkeys. The advantages of showkeys are:
- Doesn't use gtk/gnome.
- Uses libxosd to display keys directly onto the screen.
- No floating windows that always need to be on top. This is very useful if you're using a tiling WM like Xmonad.
- Keystroke history. key-mon has this but doesn't show modifiers. showkeys does using and Emacs style key notation.
