As well as two-finger clicks on the trackpad, you can also access the menu by holding the ALT key and clicking on the trackpad at the same time. You can use the two-finger or ALT+click trick to copy video URLs (e.g. to share YouTube videos) with ease. To copy an entire page, rather than just a selected snippet of text use the keyboard shortcut CTRL+A. This will copy everything and anything on the page though. If you need to copy multiple things at once then there are Chromebook extensions that can help. MultiCopy Clipboard, Copy & Paste is one example worth trying. This stores things locally so you can access them when you need them too.
