Stuck on a crossword puzzle? Crack the code with Ctrl-___-Del

The answer to the crossword question “Ctrl-___-Del is ALT” is “ALT.” This statement refers to the fact that the three keys commonly used to restart a frozen computer, Ctrl-Alt-Delete, are also sometimes referred to as “Alt-Ctrl-Del” or “Ctrl-Alt-Del.” In this case, the question is suggesting that “Ctrl-___-Del” (with the missing key being “Alt“) is the same as the commonly recognized phrase “Ctrl-Alt-Del.” This is a play on words, as the statement is technically true – if you replace the missing key with “Alt,” you do get the well-known combination of Ctrl-Alt-Delete – but it may be worded in a somewhat confusing or misleading way for crossword puzzlers.
