Is there a glossary somewhere that explains what the various strokes indicate
in Excel? For instance I know that for certain formulas I need to use " but
I don't know why...---If I knew what " said to Excel I think I could make
much better use of the program---another instance I noticed a post where
someone said "you have to use double quotes" Is there a way of understanding
in plain terms what exactly that is telling Excel to do?

I hope I'm making this clear...... I can learn by rote and just do it....but
am trying to understand Why I'm doing it, so can be better in the future.
Thanks!!!
