Keyboard shortcuts that genuinely save you hours every week

You don't need to memorize 200 shortcuts. These 12 cover 95% of daily computer use. Learn two a day:

The essentials

• Ctrl+Z / Ctrl+Y — undo / redo. Works almost everywhere.
• Ctrl+C, Ctrl+X, Ctrl+V — copy, cut, paste. (Mac: Cmd instead of Ctrl.)
• Ctrl+S — save. Hit it reflexively; future you says thanks.
• Ctrl+F — find text on the page. Enormous time saver in long documents.
• Ctrl+Shift+T — reopen the browser tab you just closed by accident.
• Alt+Tab — switch between open windows. (Mac: Cmd+Tab.)

Window wrangling

• Win+D — show desktop instantly, then bring everything back.
• Win+Left / Win+Right — snap a window to half the screen. Two documents side by side, zero dragging.
• Ctrl+T / Ctrl+W — new browser tab / close tab.

Text power moves

• Ctrl+Left/Right arrow — jump word by word instead of letter by letter.
• Shift + arrows — select text as you move. Combine with the above to grab whole words fast.
• Ctrl+A — select all.

Pick the three you don't know yet and use them deliberately for a week. They'll be muscle memory by Friday.

Bonus round: Win+V on Windows 10/11 opens clipboard history — it remembers the last 25 things you copied. Turn it on once and it's there forever. I haven't lost a copied password or address since.
