When you hold down the Control key and click on the Date Column header with the v chevron displayed and type 20040206, the focus is placed on the first transaction for 2004 then 02 (February) then the first transaction for February 06, 2004.

The opposite is true when the chevron is displayed as ^ in the date column header. The focus is on the last transaction in 2004 (earliest 2004 transaction), the last transaction in February (the earlist transaction in February), the last transaction on February 6, 2004.
