A hard refresh is a way of clearing the browser's cache for a specific page, which can help resolve issues such as loading errors or displaying outdated content. Unfortunately, there is no universal key combination to perform a hard refresh across all browsers and devices. The most common key combination is Ctrl+F5, but this may not work on all devices. Depending on the device and browser, you may need to use a different combination of keys. For example, if you are using a Mac, you may need to use the Command+Shift+R key combination. Additionally, some browsers may require you to hold down the keys for a few seconds before the hard refresh will take effect. If none of these key combinations work, you may need to manually clear your browser's cache. Instructions for doing this can usually be found in the browser's help menu.
