Hello Linux Geeksters. As you may know, Indicator Keylock is an applet for Ubuntu, compatible with Unity, Xfce, Gnome Shell and Gnome Classic, that notifies the user when the Caps lock is on. Also, it can be configured to notify the users if Num lock and Scroll lock are pressed.
The latest version available is Indicator Keylock 3.0.
In this article I will show you how to install Keylock Indicator 3.0 on Ubuntu 13.10 Saucy Salamander, Ubuntu 13.04 Raring Ringtail, Ubuntu 12.10 Quantal Quetzal and Ubuntu 12.04 Precise Pangolin.
Because it is available via PPA, installing Keylock Indicator 3.0 on the listed Ubuntu, Linux Mint, Pear OS and Elementary OS is easy. All you have to do is add the ppa to your system, update the local repository index and install the indicator-keylock package. Like this:
$ sudo add-apt-repository ppa:tsbarnes/indicator-keylock
$ sudo apt-get update
$ sudo apt-get install indicator-keylock
