Excel Merge Cells Shortcut: Alt H M M (and the safer alternative)

No single-key shortcut exists, but the ribbon keys are quick once your fingers know them.

Steps

  1. Select the cells to merge, e.g. A1:C1.
  2. Press Alt, then H, then M, then M — one after the other, not held down.

That is Merge Cells. Other endings:

Keys Does
Alt, H, M, C Merge & Center
Alt, H, M, A Merge Across (each row separately)
Alt, H, M, M Merge Cells
Alt, H, M, U Unmerge

Mac: no ribbon keys; use Home › Merge & Center, or add it to the Quick Access Toolbar.

Make a one-key shortcut

Right-click Merge & Center on the ribbon › Add to Quick Access Toolbar. If it is the 3rd item there, Alt + 3 now merges.

The safer alternative

Merged cells break sorting and selecting. Center Across Selection looks the same without the damage: select A1:C1 › Ctrl + 1 › Alignment › Horizontal: Center Across Selection. Full lesson: merge cells.

Check it worked

Click the merged area — a single selection outline covers all three cells, and the Name Box says A1.
