Get to know the basics

There are certain shortcuts I use all day, every day. They are handy if I'm doing work with photos, music, documents, or spreadsheets. These will help stop 'mouse-fatigue': Copy a selected item: Ctrl+C, Cut a selected item: Ctrl+X, Paste a selected item: Ctrl+V, Undo an action: Ctrl+Z, Redo that thing I just undid: Ctrl+Y, Select everything: Ctrl+A, Print: Ctrl+P
