Did you know that when typing, delete and backspace are not really the same thing? It’s true!
The backspace key, which I think probably gets used more often, erases letters or characters to the left of (behind) the cursor (that blinking line that shows where you are typing).
But the delete key will delete letters or characters to the right (in front) of the cursor. I find this helpful especially if I forget to capitalize the first letter of a word, or when I click into the middle of a word to correct my spelling mistakes.
Try it out! I bet you didn’t realize there was a difference.
