Turn off any content type you don’t want as input for your shortcut.
Click Clear to turn off all content types.
Optional: To choose how the shortcut responds if there is no input, click Continue in the input action and choose one of the following:
Stop and Respond: The shortcut stops and (optionally) displays a message. To display a message when the shortcut runs and there is no input, click Response and type a message.
Ask For: The shortcut asks for input. Select the content type to pass through to the shortcut.
Get Clipboard: The shortcut uses the contents of the Clipboard as input.
Continue: The shortcut runs without interruption. If an action uses the input as a Magic Variable, the variable will be empty.
