Looking at the suggested config I see that the only input is key/shortcut, while for modal editors it should also be a mode and some previous info like `2dd`. Maybe...

Anyway, the best approach is to have this in xi-core itself

Just to add my 2 cents: There are definitely cases where passing by reference do not imply mutation, like iterators or any aggregation; p.s. why `ref` instead of Rust syntax...
