4. Press the Enter key after each formula.
The time since the birthday will be calculated and displayed in the various units. The values
are calculated as of the exact moment when the last formula was entered and confirmed by
pressing the Enter key. This value is not automatically updated, although NOW continuously
changes, of course. In the Tools menu, the menu item Cell Contents > AutoCalculate is
normally active; however, automatic calculation does not apply to the function NOW. Consider
that, if it were, the computer would use all its resources updating the sheet.
When spreadsheets contain a very large amount of data or very complicated formulae that
may be modified before viewing the calculation results, it may be prudent to cancel or
disable the automatic calculation function. Calculation time naturally becomes longer as the
complexity and size of a spreadsheet increases.
Inserting and Editing Notes
A note may be assigned to each cell by choosing Insert > Note. All notes are indicated by a
small red square, the note indicator, in the cell. Notes made visible whenever the mouse
pointer is over the cell, provided Help > Tips or Extended Tips is active.
• For a selected cell, choose Show Note from the context menu of the cell. Doing so keeps
the note visible until the Show Note command is deactivated from the context menu.
• To edit a permanently visible note, just click in it. When the entire text of the note is
deleted, then the note itself is deleted.
• Another way to delete a note is by choosing Edit > Delete Contents, or calling the same
dialogue with the Delete key.
• Select Tools > Options > OpenOffice.org Calc - View to show or hide the note indicator
by checking or unchecking the Note indicator box.
