Toggle the upward diagonal border in Format Cells
Select one empty cell B2. Open Format Cells and choose the Border tab.
Start here: Windows Format Cells dialog with its Border tab active
These letters are dialog accelerators, not Home Ribbon commands. Inside-border controls need a range with multiple rows or columns. No Mac equivalent is sourced here.
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
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
- Confirm the Border tab is active before using the chord.
- Use the listed chord and inspect the border preview; use it again to check the toggle.
- Choose the intended final preview, then confirm the dialog, or cancel to leave the worksheet unchanged.
Expected result: The diagonal preview switches between absent and present; committing affects the cell border, not its content.
