+Hi! Welcome to my world, the world where text is all around and plentiful. I'm tee,
+a simple text editor that hopefully will help you in your text journey!

+Execute some of these using your mouse right button, hover over a
+word like ":New" and click!
+
+:New               (ctrl-n)       - create new text file
+:OpenUpFolder      (ctrl-o)       - navigate directories
+:ShowCommands      (ctrl-shift-p) - open up the command lister
+:ShowBufferList    (ctrl-p)       - open up a lister with open files
+
+Alternatively you can open with your keyboard - ctrl-q / f12, try that also!
