If you’re typing (in Word, Outlook, PowerPoint, and many other text entry programs) and you use the wrong word, a quick way to delete the entire word is Ctrl+Backspace.
You need to practice this one a few times to get used to it. It’s also an easy one to forget to use, but it’s worth making the effort to get the Ctrl+Backspace habit: If you type a long word and want to erase it instantly, it’s much faster to hit Ctrl+Backspace then the Backspace key by itself several times.
As an example, if you type, “I must remember to buy a new hippopotamus_” and your cursor is right after the word hippopotamus, the entire word hippopotamus is erased and your cursor is now positioned at the end of the sentence: “I must remember to buy a new_”. Then you can type “toaster” or whatever word you actually want to type.
If you’re in the middle of a word, it only deletes the portion that’s to the left of your cursor. So if you typed “Here comes the sun_king” and move your cursor (as indicated) between the “sun” and “king” portions, then press Ctrl+Backspace, what you’re left with is “Here comes the king.”
