Every program you use has a tools menu. If you use tools a lot it will be a toolbar across the top of the screen. If you rarely use tools it might be hidden. In Windows you can click "Start" and select "Control Panel" and that gives you a menu of menus to control everything the computer does. You can right click anything and most of the time get a menu for that specific item. For example if you right click the desktop you have the option to rotate the monitor image in some graphic cards. That allows you to have an image that is high instead of wide, by turning your monitor. You don't need to memorize all these things, just be aware that they are in there. Then you can claim to know how to operate a computer at the beginner level.
When you ask for help, the first thing anybody needs to know is what operating system you are using. Then you need to specify what mail client, or if you are doing web based mail then what website you are using. Whatever it is, there is a button or hyperlink someplace that plainly says "FORWARD".
If that doesn't work then you just need a friend to look at it and see what it's about.
