Ribbon keyboard shortcuts
The ribbon groups related options on tabs. For example, on the Home tab, the Number group includes the Number Format option. Press the Alt key to display the ribbon shortcuts, called Key Tips, as letters in small images next to the tabs and options as shown in the image below.
You can combine the Key Tips letters with the Alt key to make shortcuts called Access Keys for the ribbon options. For example, press Alt+H to open the Home tab, and Alt+Q to move to the Tell me or Search field. Press Alt again to see KeyTips for the options for the selected tab.
Depending on the version of Microsoft 365 you are using, the Search text field at the top of the app window might be called Tell Me instead. Both offer a largely similar experience, but some options and search results can vary.
In Office 2013 and Office 2010, most of the old Alt key menu shortcuts still work, too. However, you need to know the full shortcut. For example, press Alt, and then press one of the old menu keys, for example, E (Edit), V (View), I (Insert), and so on. A notification pops up saying you’re using an access key from an earlier version of Microsoft 365. If you know the entire key sequence, go ahead, and use it. If you don’t know the sequence, press Esc and use Key Tips instead.
