so I was writing code in Geany (decent IDE, prob best for rpi ) and I accidentaly pressed a key combination (Idk all the key combs for rpi) and It made Geany full screen. I did not have a problem at first but I needed to see the documentation for html(I am not a god at html) and I needed to make Geany minimized and I coudn't. I started pressing random key combs and I got at one that the only text was "." and I had to un-plug my rpi and then plug it in.
I lost allmost all my code.
