Delete a Whole Word or Line at Once on Mac

Holding down Delete and watching characters vanish one by one is the slowest way to fix a sentence. macOS has word-sized and line-sized deletes built into almost every text field — two modifier keys are all you need to learn.

The two shortcuts that matter

• Option+Delete — delete the entire word to the left of the cursor, plus the space before it. Tap it three times and three words are gone. This is the single highest-value editing shortcut on the Mac.
• Cmd+Delete — delete everything from the cursor back to the start of the line. Mistyped a whole sentence? One keystroke.

Try it right now in any text field: type a few words, then tap Option+Delete twice. The speed difference over held-down backspacing is immediately obvious — a ten-character word disappears in the time plain Delete takes to remove two letters, and there's no overshoot to re-type.

Both follow the same logic as cursor movement: Option means “by word” and Cmd means “by line”, whether you're moving (Option+Left, Cmd+Left), selecting (add Shift), or deleting.

Forward variants

Everything above deletes leftward. To erase to the right of the cursor:

• Fn+Delete — forward-delete one character (the missing Del key on MacBooks).
• Fn+Option+Delete — forward-delete the whole next word.
• Ctrl+K — delete from the cursor to the end of the paragraph. Whatever it removes goes into a separate “kill” buffer, and Ctrl+Y pastes it back — without touching your normal clipboard.

That last pair is a genuinely useful trick for moving text without losing what's already on your clipboard: Ctrl+K to cut the rest of a line, click where it belongs, Ctrl+Y to drop it in — your copied URL or password stays safely on Cmd+V the whole time.

Where they work — and the two gotchas

These shortcuts are part of the macOS text system, so they work in nearly every app: Notes, Mail, Safari, Messages, Pages, third-party apps with standard text fields. Two exceptions to know:

• Finder: Cmd+Delete isn't a text shortcut there — it moves the selected file to the Trash. (Inside a rename field, though, the text meaning applies again.)
• Terminal: the shell has its own line editor. Use Ctrl+W to delete the previous word and Ctrl+U to wipe the whole line — both work in the default zsh and in bash. Option+Delete can be made to work too: in Terminal → Settings → Profiles → Keyboard, tick Use Option as Meta key.

Apps with custom text engines (Microsoft Word, some IDEs) generally support Option+Delete but may treat Cmd+Delete differently — worth a two-second test in the app you live in.

The pattern behind them

Once you see the modifier logic, you stop memorizing shortcuts and start deriving them:

• No modifier — act on one character: Left, Shift+Left, Delete.
• Option — act on one word: Option+Left, Option+Shift+Left, Option+Delete.
• Cmd — act on the whole line: Cmd+Left, Cmd+Shift+Left, Cmd+Delete.
• Fn — flip the direction of a delete.

And everything is undoable: Cmd+Z restores any deletion, word-sized or line-sized, so there's no risk in practising on real text.

Make them muscle memory

Pick just Option+Delete for the first week and force yourself to use it every time you mistype a word — it covers the majority of real corrections. Add Cmd+Delete once that's automatic. The forward variants are situational; learn them when you notice yourself arrowing right before deleting.

Select before you delete

Sometimes the faster fix is selecting precisely and typing over it. The same Option/Cmd logic drives selection too — see every text-selection shortcut on Mac.
