Delete an entire word with Option+Delete
Oct 29, 2010 - 5 Comments

You can delete entire typed words by holding down the Option key while you use the Delete key.
As far as I can tell this works all over Mac OS X and in most apps, including Safari, TextEdit, Terminal, Finder, iTunes, iChat, and more.

Good one. Even works in the URL of your post. How did you find this ??
Emacs style key combinations.
I use a few others in daily work:
Option+Left/Right moves cursor by one word
Ctrl+A moves to the left of current line
Ctrl+K deletes characters from cursor position to the end of current line
This a good one. and very useful. It deletes the word BEFORE the cursor.
To delete the word AFTER the cursor on a compact keyboard (i.e. forward delete):
fn-option-delete
i already knew this. lol
Actually, it deletes all the characters from your cursor position to the next space, forward or backward depending upon which “delete” key is used. So if you cursor is in the middle of a word, it will delete only part of that word.
