Hello Linux Geeksters. As you may know, Keystroke is a keystroke visualization tool for KDE, built in Qt. It is very useful when recording your screen, because it is displaying on the screen what you are typing, with bigger letter than usual, as if you are getting subtitles.
In this article I will show you how to install Keystroke on Ubuntu 14.04 Trusty Tahr, Ubuntu 13.10 Saucy Salamander, Ubuntu 12.10 Quantal Quetzal, Ubuntu 12.04 Precise Pangolin, Linux Mint 16 Petra, Linux Mint 14 Nadia, Linux Mint 13 Maya, using the KDE desktop environment.
Because it is available via PPA, installing Keystroke on the listed Ubuntu and Linux Mint systems is easy. All you have to do is add the ppa to your system, update the local repository index and install the keystroke package. Like this:
$ sudo add-apt-repository -y ppa:samrog131/ppa
$ sudo apt-get update
$ sudo apt-get install keystroke
To start the app, just search for keystroke-gui.
