Opposite of delete

ENTER

Think of the key you press to submit a form or confirm an action on a keyboard. It’s also what you do when you join a room or competition.

"Opposite of delete" hints at the action you’d take to add or input something rather than remove it. In computing and everyday language, "enter" is the command used to confirm or submit data—essentially the reverse of deleting it. The clue plays on basic keyboard functions, where "delete" erases while "enter" finalizes, making the answer straightforward once you think of typing actions. No hidden wordplay here, just a direct contrast between two common terms.
