\label{Spreadsheet_Cell_Editing}

To edit a cell in the spreadsheet, move your mouse pointer over it until you 
are able to follow a link.  Click on the link to open up an editing window.  
The current contents of the cell will be shown and can be modified.  
Pressing the \fbox{Accept} button will cause the spreadsheet to be updated with 
the new formula.  
You will then be working with an unsaved modified copy of a spreadsheet.  
See \textbf{Spreadsheet Files} (\ref{Spreadsheet_Files}) for information on 
loading and saving spreadsheets.
Pressing the \fbox{Discard Changes} button will discard any changes you have
made to the contents of the cell.

\noindent
\textbf{What goes in a cell}

The cells of the spreadsheet contain a mixture of Perl commands and LON-CAPA
specific functions (\ref{Spreadsheet_Functions}).  
Most non-IO Perl functions work in cells.
