Hi,
Regarding Ctrl+A: If you are running 2003 and your cursor is in data,
Ctrl+A selects the data, not the entire worksheet. To select the entire
worksheet press Ctrl+A twice. If you are in 2007 and your cursor is in a
Table, then Ctrl+A selects the data in the table. If you press Ctrl+A a
second time from within the table the entire table, including titles are
selected. To select the entire worksheet from inside a tabe press Ctrl+A
three times.
To avoid this confusion just click the top left corner of the worksheet, the
intersection of the row numbers and column letters.
