Instructions

A practical guide to capturing, editing, and using screenshots with FastShot on Mac and Android. Everything stays on your device.

macOSMenu bar, hotkeys, scroll capture, editor, OCR AndroidPermissions, floating button, Quick Settings tiles

macOS

FastShot lives in your menu bar and can capture any screen, window, or selected area. After capture you can annotate, copy, save, pin, or run on-device OCR.

Requirements: macOS 12.3 or later · Apple silicon or Intel.

1. Allow Screen Recording

  1. Open System Settings → Privacy & Security → Screen Recording (on some versions: Screen & System Audio Recording).
  2. Turn FastShot on.
  3. If macOS asks you to quit and reopen the app, do that once.
Without this permission, captures stay blank or fail. You can revoke access anytime in System Settings.

2. Capture something

Use the menu-bar icon, the app window, or a global hotkey:

By default, FastShot can copy the result to the clipboard and open a preview so you can edit right away. Change this in Settings.

3. Scrolling screenshots

  1. Start an area or scroll capture and frame the content you want.
  2. Inside that frame, scroll the target app yourself — vertically, horizontally, or both.
  3. Scroll steadily so neighboring frames still overlap a little.
  4. Choose Done when finished. FastShot stitches the frames locally.
Keep the selection over the scrolling content only. UI chrome outside the frame is ignored. If a seam appears, recapture with slower scrolling and more overlap.

4. Edit, OCR, pin, and save

5. Default global hotkeys

These work system-wide after Screen Recording is allowed. Customize them anytime in Settings → Hotkeys.

⌥A Full screen ⌥W Area ⌥E Window ⌥S Vertical scroll ⌥D Horizontal scroll

Editor shortcuts while previewing a capture:

⌘C Copy ⌘S Save ⌘Z Undo ⌘⇧Z Redo Esc Cancel selection

6. Useful settings

Android

FastShot can capture from other apps using Android’s screen-capture permission, a floating button, Quick Settings tiles, and notification actions.

1. First-time setup

  1. Install FastShot from Google Play.
  2. Open the app and complete onboarding.
  3. When Android asks to start capturing your screen, allow it. This is the MediaProjection prompt — required for system-wide screenshots.
  4. If you want the overlay button, allow Display over other apps (draw over / appear on top).
  5. Optional: allow notifications so capture actions stay one tap away.

2. Ways to capture

Android may stop background capture after a reboot or battery optimization. Open FastShot once, grant capture again if prompted, and exclude the app from aggressive battery savers if captures stop unexpectedly.
