Let's leave [Cntrl-o] to the Midnight Commander

[getreu]

Helix like Vim assigns [Cntrl-o] to the jump_backward command. This command is especially useful when working with LSP.

Unfortunately Midnight Commander mc hard codes [Cntrl-o] to return from its inner shell. Since mc is the perfect complement for console based text editors, the only way to combine both, is to remap the [Cntrl-o] key in Vim/Helix.

It took me some time to find a disposable control key combination, close to [Cntrl-i] (jump forward) and in Vim I finally ended up with:

nnoremap <C-j> <C-o>
inoremap <C-Space> <C-x><C-o>

This way, you can browse with [Cntrl-j] and [Cntrl-i] the same way as you do with j and k.

The downside is, that [Cntrl-j] is by default assigned as second [Enter] key to insert_newline. However, as the [Enter] key is always in a comfortable position on most keyboards, I believe [Cntrl-j] rarely (if ever) used.

Proposal for Helix:

set by default:

[keys.normal]
C-j = "jump_backward"

For VIM compatibility the C-o = "jump_backward" could stay.

Furthermore, in Window mode [Ctrl-o] is assigned to Only keep the current window, closing all the others wonly. No idea what to do with this. Maybe assign it to [Alt-o] instead?

What do you think? How do you use Helix with Midnight Commander?
