Does using ctrl+c instead of esc to exit insert mode break anything in vi

vivim

When using vi, you can exit insert mode with Ctrl + C instead of the more traditional Esc. Are there any situations where it would be undesirable to use for former instead of the latter? Does it break anything other than best practice?

Best Answer

Ctrl-C and Esc are not the same in vi/vim in most modes, including insert mode. The difference is Esc triggers abbreviations while Ctrl-c does not. Whether this matters to you depends on whether you or any plugins you use make use of abbreviations.

Note that it is safer to assume Esc and Ctrl-C do not mean the same thing in vim. Another example from this same site is when exiting block insert mode (not in vi).
