Why does my ZunShot hotkey not work?

ZunShot is not running, or another program registered the same key. Check the tray icon and Settings > Hotkeys.

My keyboard has no Scroll Lock. How do I start Instant Capture?

Use Alt+PrtScn, or assign another key in Settings > Hotkeys.

PrtScn opens the Windows Snipping Tool instead of ZunShot.

Turn off the Windows option that reserves PrtScn for screen capture, or let ZunShot do it when you assign the key.

A hotkey does not work

Hotkeys are registered by the running ZunShot instance. If another program owns the key, or ZunShot is not running, nothing happens.

ZunShot Settings, Shortcuts tab, where each capture hotkey is assigned

1. Is ZunShot running?

Look for the tray icon. Closing the main window keeps ZunShot in the tray, but Exit stops the hotkeys. Turn on Enable screen capture when Windows starts in Settings > General to have it ready after sign-in.

2. Another program owns the key

Only one program can register a global hotkey. Change the key in Settings > Hotkeys, or close the other program. A second ZunShot instance also counts.

3. My keyboard has no Scroll Lock

Many laptops need Fn+Scroll Lock or have no key at all. Use Alt+PrtScn, which is also assigned to Instant Capture by default, or assign any other key.

4. PrtScn opens the Windows Snipping Tool

Windows can reserve PrtScn for its own Snipping Tool. When you assign PrtScn in ZunShot's settings, ZunShot asks for permission to turn that Windows option off and turns it back on when you stop using PrtScn. In the Microsoft Store version turn it off yourself: Windows Settings > Accessibility > Keyboard > Use the Print screen key to open screen capture.

5. The key works in some apps but not in games

Games running as administrator do not receive hotkeys from a normal process. Run ZunShot as administrator for that session, or use windowed mode.

Default keys are listed in the guide under Settings - Shortcuts.
