My command line has disappeared before...but in the past I have been able to get it back. Either by way of ctr-9 or shut-down and re-open. This time no such luck! It seems to be really gone. Toggling ctr-9 on and off doesn't seem to help. When ctr-9 is "on" and I start typing a command, I see options to complete my command in the extreme upper left of my screen, but no actual command line once I complete the command. I have resized and moved everything looking for it.
Sorry if this answer has already been answered. I spent a solid half-hour searching the forums, but haven't found anything recent or relevant.
Thanks in advance,
Sarah
