Capture a Window

nitpin captures any macOS window: your browser, the iOS Simulator, an Android emulator, a native app. Two modes cover two situations, each with its own global hotkey. They extend Apple’s ⇧⌘3/4/5 screenshot family and work system-wide while nitpin is running.

Deliberate capture — ⇧⌘6

Press ⇧⌘6 (or click Capture a window in the menu-bar popover, or Capture Window in the Cockpit). The screen dims and a crosshair appears; hovering highlights capturable windows Safari-style. Click one to freeze it into the annotation editor.

Use this when you have a moment to aim. It’s the everyday mode.

Quick capture — ⇧⌘7

Press ⇧⌘7 and nitpin freezes the window under your cursor immediately, before any overlay appears, into a lightweight non-activating editor. Because nothing steals focus first, the UI you’re pointing at survives the capture.

Use this for transient UI: open menus, tooltips, popovers, hover states, drag previews — anything that vanishes the moment your app loses focus. (A beep means there was no capturable window under the cursor.)

Good to know

• Both hotkeys are configurable in Settings › General › Capture. If a combo is already taken by another app, nitpin shows a warning and asks you to pick another.
• Capture is paused while the Settings window is open.
• Capturing never touches the target app. nitpin reads pixels and window metadata (the app’s name and window title, saved as the issue’s provenance) and nothing else.
• For web apps, there’s a third way that skips windows entirely: Live mode.
