"sudo !!" is quite firmly burnt into my muscle memory, but the whole rest of the time when I type an exclamation mark I mean it literally, and I get annoyed when it turns into a syntax error of some variety.
replyWorse, the "press up-arrow to get the previous command, then fix the errors in it" flow is broken when an exclamation mark causes a syntax error.
replyAs an Emacs using degenerate, `M-.` is my friend. `!` is too awkward on the keyboard.
replyI guess you could map it to the right-hand M key?
replyAs someone who can type rather quickly, I disagree. It can take some time to internalize, but once you do, it's much faster.
replySame with Ctrl-C - once I got used to navigating by word instead of by character to correct things, it became much faster than starting over.
