Duplicate Shortcut
Duplicate a file in Finder: ⌘D on Mac. In most apps and on Windows, Ctrl+D duplicates the selected object.
| Action | Mac | Windows | |
|---|---|---|---|
| Duplicate file (Finder) | ⌘D | Ctrl+C then Ctrl+V | |
| Duplicate object/slide | ⌘D | Ctrl+D | |
| Duplicate row (Sheets/Excel fill-down) | ⌘D | Ctrl+D | |
| Duplicate tab (browser) | ⌥click reload | Alt+click reload |
Files vs objects
In Finder, ⌘D makes a copy of the selected file beside it. On Windows there's no single file-duplicate key — use Ctrl+C then Ctrl+V in the same folder.
Inside apps
Many apps map ⌘D / Ctrl+D to duplicate the selected slide, shape or layer. In Excel and Google Sheets, ⌘D / Ctrl+D fills the cell above down into the selection.
