I typed in the following, as displayed in the online help:
Cell["This is some text.", "Text", CellFrame -> True, Background -> GrayLevel[.8]]
I then pressed Shift-Return, but I only get:
Out:= Cell[This is some text., Text, CellFrame -> True, Background -> GrayLevel[0.8]]
In other words, the cell doesn't display. Why not? How do I get the cell to display?
Also, in general, if I plan to publish a notebook, how do I get just the output to display, and not all the "In[n]:=" and "Out[n]:=" to appear? Is this spelled out in the online help somewhere?
