Nice, this one was on my mind for a long time, thanks for picking it up. @Semak12345
One structural request before we land this: could the shared bindings get their own section?

keybindings.rs has four shared sets.
Right now they're all filed under Emacs with Vi insert referring back in prose, which means:

• the "Emacs-only ... such as" list is non-exhaustive, so you can't tell what
  Vi insert has
• Ctrl-Shift-x/c/v are under Emacs → Selection, but they're in add_common_edit_bindings, so also in Vi insert, absent in Vi normal/visual
• Vi normal lacking the common edit bindings is only implied by subtraction

A ## Common bindings section (one table per add_common_*) would move the
tables mostly verbatim.
