Ctrl-[ is an escape key combination that produces the same result as the Esc key by sending an ASCII escape character, and it is commonly used as an alternative in programs like the vim editor and in SSH terminals. The original design of the ASCII character set is the reason why pressing Ctrl plus a letter or symbol produces a different character code; for example, Ctrl-[ sends the code for escape (\(27\) or \(0x1B\)).
