I typed and evaluated an expression, but deleted it from the notebook. For instance, suppose it was
In:= Round@SessionTime Out= 2
I now want to retrieve the input so that I can edit it again.
I know Mathematica keeps the history of evaluated expressions in
In. But if I try to access it directly
In, rather than giving the unevaluated input expression, it evaluates it again:
In:= In Out= 10
If I use
Hold to suppress evaluation, then
In[...] doesn't get evaluated, so I don't see the input:
In:= Hold[In] Out= Hold[In]
How can I retrieve the input expression in an editable form, without evaluating it?
