Hi,

Very often, when editing (and debugging) my notebook, I change temporarily the value of a variable. It is not always a good solution to change it in a cell, as I often forget about the temporary change, and could forget to revert it back. My current solution is to have a "scratchpad section" at the end of the notebook, with cells that I only execute to tweak the value of a variable without altering it in its cell, which I expect to remain correct.

What about offering the ability to type some instruction live, in a scratchpad cell (that could be triggered by a shortcut and discarded after execution)?
