If you have become bored with an object, simply select it and then click on this icon. Naturally you can also delete several frames at once. In each case a safety alert appears to allow you to change your mind at the last instant.
Tip: You don't always have to delete it. If you cut an object from the page and store it in the clipboard (see Clipboard module), it will still be available for use on this or other pages. Naturally at some time the clipboard will become completely filled, so that you should tidy it up from time to time.
