| Call: | Get PreviousColumn (&hoCol) (&bWrap) to BooleanVariable |
When the user presses the Shift+Tab key to move to the previous column, the Previous message is called. This message determines what that previous column should be by calling the SelectedColumn object's PreviousColumn message. PreviousColumn must find the appropriate column by taking into account the current column display order, a column's visibility and a column's ability to take the focus during previous keyboard navigation. PreviousColumn performs this task by sending the message CanNavigateIntoColumn to each column in the column display order until it finds a suitable column. It then returns whether a previous column exists and, by reference, the previous column object and whether the previous column is in a different row.
