[I have not yet found an acceptable multi-screen replacement for 
Terminal.]  Given the small OLPC screen, what I do is start two 
instances of Terminal - then use one to "read" information (i.e., 
for 'reference') and the other to "write" what I'm working on (i.e., 
for 'output').  This usually involves a lot of navigating back and 
forth between these two Terminal instances.  "Cycling around" seems 
very cumbersome (and it actually is time-consuming).  Maybe one of 
these years I'll write some scripts to 'select' each instance, then 
attach them to keyboard keys.  That should give me good "operator 
performance" - a single keypress and I get to a specific instance.
