What are the 10 most often used functions in Sage?

edit

Looking at the file

$HOME/.sage/ipython/history-sage

I see that my common recent commands are:

NumberField, ModularSymbols, factor, timeit, EllipticCurve

plot() has got to be pretty high on the list, and maybe all of these require var()!

print
__init__
cached_function

• search_*
• tutorial()

• hg_sage -- I use this all the time, although of course you can run hg outside of Sage to accomplish the same thing.
• time and timeit
• SteenrodAlgebra -- well, I use it frequently, anyway...

help and ?? ;-)

plot/list_plot

simplify/simplify_full

print

view

solve

It definitely depends on the person. For me, probably, the top four commands are _.<t>=QQ[], NumberField, EllipticCurve, and ModularSymbol.
