Your course can add its own keys with the trigger event **Key pressed**. If you use one of the keys above in a trigger, your trigger wins on that slide. ## If something doesn't work **A shortcut does nothing.** The cursor is probably in a text field, or a dialog or menu is open. Press or click on an empty spot of the stage, then try again. **The browser does something else instead (for example a bookmark or a new window).** Some browsers keep certain key combinations for themselves. Use the button in the ribbon instead; its tooltip shows the shortcut. ## Sitemap See the full [sitemap](https://docs.ols.yonn.online/sitemap.md) for all pages.
