Yes, use your mouse better and start right-clicking on things. If you are not in the habit of doing that you are missing a lot of convenient help at the (right-)click of a mouse!
Start now. Say you are looking at an image file (a picture), say it’s called img10023.jpg, right out of your camera, right-click on the file name. The menu that pops up shows you what you can do with the file. In the menu there is probably an option to ‘open with’, ‘edit with [photo editing software]’, ‘cut’, ‘copy’, ‘delete’, print, or ‘rename’ the file. So one right-click shows you right there, what you can do with the object (=file). That goes for all objects on your screen. Right-click on everything, you’ll learn a lot in a short time.
On the left is an example, some of the menu options will not apply to you, because your computer would have different software installed.
With learning come mistakes. So one other indispensible keyboard shortcut you need to know by heart is: ‘Ctrl + Z’ for ‘UNDO’. What would we do without ‘undo’?
