To do Alt + I N D on Mac in Excel, install Accelerator Keys, then press Option, then I, then N, then D. It runs the Excel 2003 command Insert > Name > Define.
If you are looking for the Alt + I N D shortcut on Mac Excel, you may know it from Excel 2003, where Alt + I opened the Insert menu. Windows Excel still accepts these menu keys. With Accelerator Keys, they work on your Mac too.
Alt + I + N + D is the legacy shortcut for Insert > Name > Define. It opens the Define Name dialog. You give the selected range a name, such as SalesTotal. Then you use that name in formulas in place of the cell address.
On your Mac, Accelerator Keys runs Insert > Name > Define Name in the Excel menu bar. It works on any ribbon tab and at any window width.
No. Excel for Mac’s own KeyTips do not support the legacy Alt + E, Alt + I, Alt + O, and Alt + D menu keys. Accelerator Keys adds them. Press Option, then I, then N, then D.
