Selection · original practice scenario
Extend a selection right by one screen
In a wide worksheet with no merged cells or frozen panes, select C4 and note the visible rightmost column. Keep the Excel window size fixed.
Start here: Windows worksheet grid, starting away from the right edge with a single active cell
Do not expect a fixed cell count or the end of a data region. The Mac source conflict remains unresolved; no Mac recall answer is supplied.
Follow these instructions in your own desktop Excel workbook. This page explains the operation; it does not send commands to Excel.
Mac keys and context
Windows only in this catalog. The publisher Mac key table uses Option while its prose says Command is required and Option does not work; that conflicting Mac binding is withheld.
This catalog has no verified Mac binding for this operation. The steps below describe Windows. Choose Windows to use the walkthrough and recall controls.
Walk through the operation
- Select C4 in the worksheet grid and leave any formula editor.
- Hold Alt and Shift while pressing PageDown once.
- Inspect the horizontal extension from the original C4 anchor.
- Release the keys and click C4 to reset the selection.
Expected result: The selection extends right by one visible screen from its original anchor. The number of included columns depends on window width, zoom and column widths.
