New description:
Using Sage, you are missing a feature of the Magma command line interface.
In Magma, if you enter a line found in history using up arrow key and then
press down arrow key, then the next line in history is fetched. This
feature allows you to fetch as many successive lines in history as you
like. However, Sage does not have a similar feature. The
[http://ipython.scipy.org/ IPython] command prompt uses the readline
library (via pyreadline), which evidently does not support this feature.
Magma has its own custom “readline-like” library, which does support this
feature. (Since so many people have requested this feature, if anybody can
figure out how to implement it, then such an implementation would
certainly be welcome!)
See instead #12503.
