Except if there's a lot of output, or you want to go back more than one
command, it's sometimes hard to find your previous command in the first 
place.

As for snarfing commands before sending, that doesn't work if you 
want to go back several commands.  And I usually don't know I need to 
redo a command until I see something weird later in its output or 
elsewhere.

What about having a keystroke or something which just scrolls rc's window
back and positions the cursor exactly on the previous command ?  Hit it
multiple times and scroll back to earlier commands.  Then you could edit
them in place and send them just as before.  I had been thinking I might 
try it as a way of learning rio.

Or is there some way of doing something similar already?
