My Excel spreadsheet only allows the user to enter data in a narrow range of cells in one column (say B2...B10). If I press "cursor down" in the bottom cell (B10) the focus jumps back up to B2; if I press "cursor up" in the top cell (B2) it jumps to B10; this makes it difficult to scroll to the top or bottom of the list. How can I (using VBA I assume) halt the focus when it gets to the bottom or the top of the allowable range?
