Everyone knows copy-paste. Past that, most people reach for the mouse for things they do a hundred times a day. Learn these and the mouse starts gathering dust.

Universal

• Ctrl/Cmd + C / V / Z — copy, paste, undo
• Ctrl/Cmd + Shift + T — reopen closed tab
• Ctrl/Cmd + L — jump to the address bar

Windows

• Win + D — show desktop
• Win + V — clipboard history (paste something from 10 mins ago)
• Win + Shift + S — snip a screenshot of any region

Mac

• Cmd + Space — Spotlight; type an app or file, hit enter
• Cmd + backtick — cycle windows of the same app
• Cmd + Shift + 4 — screenshot a selected area

Text editing

• Ctrl/Alt + Backspace — delete the whole word behind the cursor
• Ctrl/Cmd + Arrow — jump by word, not by character

In the browser

• Ctrl/Cmd + T — new tab
• Ctrl/Cmd + 1…9 — jump to that tab

You won’t remember them all at once. Pick two, use them until they’re reflex, then add two more.
