A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
The behavior difference comes from how the shortcut is defined in each app/platform, not from a bug in OneDrive/SharePoint.
From the documented shortcuts:
- In PowerPoint for Mac (desktop app), deleting one word to the left uses ⌘+Delete, not ⌥+Delete. The documented mapping is:
- Delete one character to the left: Delete
- Delete one word to the left: ⌘+Delete
- Delete one character to the right: Fn+Delete
- Delete one word to the right: ⌘+Fn+Delete
- In Word for the web, word-level deletion is handled differently and relies on browser/OS behavior plus the app’s own key handling. The web app’s documented shortcuts focus on character-level delete/backspace and navigation; word-level delete via modifiers is not standardized the same way as in the desktop apps.
Because of this, using ⌥+Delete in the Mac desktop PowerPoint app is not a supported “delete word” shortcut and can lead to the inconsistent behavior being observed (for example, partial deletion or leaving the caret in an unexpected position, which then makes continued typing look like a typo). In contrast, Word (desktop and web) and Outlook for Mac align better with macOS text-editing conventions, so ⌥+Delete behaves more as expected.
To get consistent behavior in PowerPoint for Mac when deleting whole words, use the officially supported shortcut ⌘+Delete instead of ⌥+Delete.
