What does the command 'Insert + Space' do in NVDA?

The command 'Insert + Space' in NVDA is used to toggle speech on and off. This means that when you press this key combination, it allows the user to start or stop the screen reader’s voice output. This functionality is particularly useful for users who want to quickly pause the reading of content without changing any other settings or impacting the functionality of the screen reader.

In a practical scenario, if a user is listening to a web page but needs to quickly stop the speech to follow a visual element or to read something on the screen without audio distraction, this command gives them the flexibility to manage their listening experience effectively. It’s a key feature for users navigating digital content, allowing them to have control over the screen reader's feedback.
