Most operating systems have a lot of really useful shortcuts that most people don't use despite it potentially making their lives 10x easier like Ctrl/Cmd+C. Swipe to undo, holding down the key to access accented keys (also works on address bars as it prompts you to add common domains like .com or .net), slide to type, etc. An easy way to discover most of these (on iOS specifically) is just to go through the working with text section in the iOS Tips app.
