Feature suggestion - command history accessible with up and down keys (bluetooth keyboards have them)

One feature I miss while using Text Fiction is the command history.  Each command the user submits is recorded and all recorded commands can be iterated through by hitting the up and down keys.

FYI, I mostly use this feature when I mistyped a command.  I  bring the command back and adjust it, before submitting it again,

I also use it to help me remember what I said a while back.
