Up arrow seems to be working
Down arrow works. I think. As much as it will.

- Will have a bug at the end of some lines. At the end of the top
line, going up it will go to the start of the textarea instead,
then up. At the end of the second to last line, going down it
skip the last line. This is due to indexing if cursor position,
not sure how to combat it
Test/ghost area not visible, cleans up some leftover comments
