Windows The most comprehensive Word shortcut set. F-key shortcuts work without Fn: F7 for spelling and grammar, F12 for Save As. Ctrl+Alt+1/2/3 applies heading styles. Alt activates Ribbon key navigation for any command not covered by a direct shortcut. Ctrl+Shift+E toggles Track Changes on and off.
Mac Uses Command (⌘) as the primary modifier. Cmd+Option+1/2/3 applies heading styles — the Mac equivalent of Ctrl+Alt on Windows. F-keys require Fn by default unless you've changed macOS keyboard settings. Tracked changes and review shortcuts are available and covered.
Web Runs in a browser on any operating system. Modifier key follows your OS (Command on Mac, Ctrl on Windows). Most core shortcuts work; some advanced review and formatting features have limited web support.
iPhone Requires an external keyboard. Covers text formatting, navigation, and basic editing. Tracked changes review is available in the Word mobile app with limited shortcut support.
Android Requires a Bluetooth keyboard. Uses Ctrl as the modifier, following Android convention. Coverage is similar to iPhone.
