What you'll be able to do

A few shortcuts do most of the work
You do not need to memorise dozens of key combinations. A small handful covers most of what you do all day. A keyboard shortcut just means holding one key while you tap another, so the computer does something without you reaching for the mouse. On Windows you hold the Ctrl key (bottom-left of the keyboard, short for Control). On a Mac you hold Cmd instead (the key next to the spacebar, short for Command). Everything below works the same way on both; just swap Ctrl for Cmd.
Copy, cut, and paste without the mouse
These three move text or files around. First, select what you want by dragging over it or clicking it. Then Ctrl+C copies it (leaves the original where it is), or Ctrl+X cuts it (removes it, ready to drop elsewhere). Move to where you want it and press Ctrl+V to paste. A handy partner is Ctrl+A, which selects everything at once, useful when you want to copy a whole document or an entire list. Copy is safe to practise with, because it never changes the original.
Undo and redo are your safety net
This is the one that saves you the most stress. Ctrl+Z undoes your last action, whether you deleted a paragraph, moved a file, or typed over something by mistake. Press it again to step further back. Went one step too far? Ctrl+Y (or Ctrl+Shift+Z on a Mac) redoes what you just undid. Because undo is right there, you can try things without worry. If something looks wrong, undo it and you are back where you started.
Save often, and switch windows smoothly
Ctrl+S saves your work. Many apps save automatically now, but plenty still do not, and a quick Ctrl+S every few minutes means a crash or a power blip costs you seconds, not hours. Make it a reflex: finish a thought, tap Ctrl+S. When you are juggling several windows or tabs, Alt+Tab on Windows (Cmd+Tab on a Mac) flips between open programs, and Ctrl+Tab moves between tabs inside one window. A little practice and your hands will find these without you looking.
Common questions
What is the difference between Ctrl and Cmd?
They do the same job on different computers. Windows keyboards use the Ctrl (Control) key, and Mac keyboards use the Cmd (Command) key. Wherever you see Ctrl in a shortcut, use Cmd on a Mac and it will work the same way.
What is the difference between copy and cut?
Copy (Ctrl+C) makes a duplicate and leaves the original in place. Cut (Ctrl+X) removes the original so you can move it somewhere else. Both put the item ready to paste with Ctrl+V. When you are not sure, use copy, because it never removes anything.
I made a mistake. Can I undo it?
Usually yes. Press Ctrl+Z (Cmd+Z on a Mac) to undo your last action, and press it again to keep stepping back. If you undo one step too many, Ctrl+Y redoes it. Undo works in most apps, so it is worth trying before you assume something is lost.
