Heading styles. Applying paragraph heading styles by keyboard is one of the highest-value Word shortcuts for structured document work. On Mac:
- Cmd+Option+1 applies Heading 1
- Cmd+Option+2 applies Heading 2
- Cmd+Option+3 applies Heading 3
These are the Mac equivalents of Ctrl+Alt+1/2/3 on Windows, the same action, different modifier combination.
F-key behavior on Mac. Word uses F-keys for a few operations (spell check, Save As, and others). On macOS, these require Fn by default. As with other Office apps on Mac, you can change this behavior in System Settings → Keyboard. For regular Word use, the Command-based shortcuts cover most operations without needing F-keys.
Document navigation. Cmd+Home jumps to the beginning of the document; Cmd+End jumps to the end. Cmd+Arrow moves by word (left/right) or paragraph (up/down), following macOS text navigation conventions.
Tracked changes on Mac. Word for Mac supports track changes review with keyboard shortcuts for toggling tracking on/off, accepting and rejecting changes, and navigating between marked changes in the document. These are covered in the table above.
Find and Replace. Cmd+H opens the Find and Replace dialog in Word on Mac, note this is different from macOS's own Cmd+H which hides applications; Word captures this shortcut for its own use.
