Describe the bug

imap jj <Esc> in init.vim not working at all.
neovim can correctly jump to normal mode by jj.
but the setting isn't effective with ShadowVim

How to reproduce?

1. open any file in xcode
2. type jj to switch to normal mode
3. jj shows on the screen which is not expected

That's expected, because the Insert mode since 0.2.0 is handled by Xcode, so the imap bindings are not triggered.

But I know that the imap jk <Esc> binding is really popular so I think I will implement the imap support directly in ShadowVim at some point. However I have plenty of other subjects to tackle first (e.g. : prompt) so I don't know when it will be supported.

Personally I use the Caps-lock key as an alternative to Esc, thanks to Karabiner Elements. But if you really can't live without imap, you can add this autocmd in your Neovim config:

autocmd InsertEnter * SVSetInputNvim

This will let Neovim handle all keyboard events, even in Insert mode. This is not recommended though, as it might mess up Xcode's auto-completion and indentation as well as typing performance.

By the way are you using Chinese characters in your source code? I'm afraid there might be some issues because I'm not entirely sure the character ranges from Neovim are compatible with the ones from Xcode's Accessibility API.

Thanks.
