How about being able to recall from the history via number:
gnuplot> history 5
162 myval = 123
163 show vars
164 show variables
165 plot x + myval
166 history 5
gnuplot> history !165
^
not in history
which would be useful if the history gets quite long and the user wants to recall a long ago command that is very similar to one more recent?
