Thank you for working on SpaceVim! :)

I preserved indentation in shell.vim, despite the conventions, because it existed there. Let me know if you prefer I don’t adapt spacing.

Why this change is necessary and useful?

Fairly often, you need to send the <Esc> key in a terminal, especially with fzf to cancel current input. I think this change provides an handy way to do this, without changing existing habits.

Ping 😁 ?

exe 'tnoremap <silent><esc><esc> <esc>' will make <esc> slow. vim will wait for second key.

[cljoly]

That’s true. Perhaps another keybinding would be more suitable?

[wsdjeg]

@cljoly hello, maybe we should remove tnoremap <silent><esc> <C-\><C-n> in spacevim.

[cljoly]

I think it would be a good idea to replace it with another binding too.

[wsdjeg]

@cljoly Hi, we will add new key binding ctrl-` to toggle terminal windows. and the esc will not be mapped any more. so this issue will be fixed soon.

[cljoly]

That’s great, thanks @wsdjeg !
