Install a software keyboard in Linux Lite?

[gotLL]

Hello,
I would like to try and use Linux Lite for an older PC dedicated to feeding a Television.
It would be cool to have a pop-up software keyboard that I could control via mouse.

I don't think Linux Lite comes with any software keyboard by default
I installed the Maliit software Keyboard - but can't figure out how to get it running.

Any suggestions?

Thanks in advance
