If you’ve ever received an Adobe InDesign file from another designer or client that you need to work on, and upon opening found the document pages absolutely covered with useless Guides (Don’t you just hate that?), this little tip will ease your pain, and clear the document of unsightly and largely unnecessary guides. Rather than deleting guides one at a time, hit Command + Option + G then Delete. This selects all the guides on the page and deletes them. If you find the guides locked into position, hit Command + Option + ; to unlock them before selecting and deleting them.
