Ctrl+C requires taking your fingers off homerow and pressing two keys at once, though.
Granted, escape also meets those criteria if you map it to the caps lock key, which I do. The jk mapping is still useful in the rare occasions I use vim on my phone, though.
+1 for remapping Caps Lock to Esc.
It is easily done in GUI settings in both MacOs and most Linuxes and it is quite useful to have it there OS-WIDE.
In the rare cases I need to Caps Lock it is still available by pressing both shift together (there are various Linux options around that)
I never bothered to have it map to Ctrl on holding the key in addition of Escape on pressing but it is easily done. There's at least on blog post about that if you search HN
I remap caps lock to ctrl on my OS which does make it a little more ergonomic, but I still prefer your method. Although, whatever wizard taught me vim and gave me their beginner cheat sheet had jj instead of jk.
In my case, I agree, but when I asked about this key combo once elsewhere, a number of folk pointed out that this is true for the standard US QWERTY layout, but not necessarily so for various EU or other layouts.
AltGr+8 is reasonable enough that I don't feel like learning a new layout.
Ctrl+AltGr+8 is involved enough that I might as well press Esc.
A lot of software developers are unaware of the AltGr[1] key or even assume US ANSI layout altogether so as a user I have been trained not to take keybindings involving that layer for granted.
As a real world example of similar issues, there's piece of software (I think it was telnet or mosh, but I apologize if I misremember) where Ctrl+^ is used as an escape sequence. This doesn't work for me, possibly because caret is a dead key[2] on my keyboard. For some reason, perhaps related to using scancodes instead of key codes, Ctrl+6 happens to work in that application.
ctrl-c is not the same as escape. ctrl-c doesn't trigger the InsertLeave autocmd or abbreviations. This may not matter to everyone but it's worth being aware of.
