Capture
Each kind of capture has its own shortcut. The defaults use Option-Shift-Command so they never clash with the Mac's own.
| Capture | Shortcut |
|---|---|
| Area: drag over what you want | ⌥⇧⌘4 |
| Window: click a window | ⌥⇧⌘5 |
| Fullscreen | ⌥⇧⌘3 |
| Annotate Clipboard Image | ⌥⇧⌘7 |
| Open Image…: edit a file | ⌘O |
Window shadow
To leave the window's shadow out of window captures, turn off Include window shadow in Settings › General.
