This feature doesn't currently exist.
Some partial workarounds:
(1) copy the cell, then each time you want to get it back, paste it.
(2) instead of having lots of big copies of the same input, define a
function, e.g.,
def foo(a, b):
some code...
and call foo repeatedly. Your worksheet will look a lot cleaner, and
there is less chance of error.

There's no equiv of %edit in the notebook, per se. You can upload and
edit files using codemirror though.
Just attach the file, then click on it to get the editor.
