You can also load up your display settings if you prefer the tedious method: ![](/files/-M24_ZqiYOJ24UyLkEwp) ## Freeze Screen Look for a button on your remote that says Freeze Screen. If you're going to draw on the screen, it's a great way to hold everything still. You can also freeze the screen if you had to bring up a file or modify attendance and you didn't want students distracted by the brief bit of business you had to do. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://gilmour.online/lancertech/educators/essential/projectors-and-tvs.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
