Mouse & Keyboard On Screen Displayer for OSX El Capitan?

Nowadays in my classroom I show video tutorials that I made for my students related to CG-apps, Excel, etc. using a utility that shows keyboard and mouse combinations named Moukey. for some cases like on a projector in the classroom it doesn't detect my Windows 10 and I don't want to call the technician. Also, I mostly like using OSX (of my dual boot MAC), sometimes and I'm looking for an OSX El Capitan version of this Key and Mouse Stroke Displayer.

In conclusion, I'm looking for an OSX Version that can display mouse and Keyboard keystrokes/combinations with mode signs similar to Moukey. If it exists please give me the name of it so that I can search it in iTunes apps.
