Keyboard modifiers state indicator for Ubuntu Unity desktop. As current state, it's just a prototype.

Unity lacks such accessibility tools which most likely needed when sticky keys is activated.
See How to add a keyboard modifier state applet to Unity panel?.

Note: May be better if you look for native extention, so try first https://github.com/sneetsher/Keyboard-Modifiers-Status

Currently, it can be run only in label mode (-l) using gnome-shell-extension-appindicator which integrates Ubuntu AppIndicators and KStatusNotifierItems into Gnome Shell.

The extension could be installed easily from https://extensions.gnome.org/extension/615/appindicator-support/ .
