Ability to scroll through dataframe or series for viewing
I think it would be nice to be able to scroll through a DataFrame by calling whatever scroll function and then holding down the up or down arrow to scroll through the different rows in a series or dataframe and the left and right arrows to scroll across various columns.  Currently, it's a little cumbersome to type in different index ranges if you want to quickly look at different parts of a dataframe ala df[0:60], then df[60:120], etc.
