Well, I started off my post with exactly that, but figured that
Greg already figured that out and wanted something more elegant.
The easiest way to do this is to just get a tab character
somewhere that you can copy, and then paste it in.
In [1]: print("\t")
In [2]: # I copy pasted the output of the cell above here
Then I also gave the alternative of using
get_ipython().set_next_input("\t Your code here")
wich will create a new cell with a tab and your code.
