How to disable backspace and delete keys in Vim?
vim
Solution
You can disable individual keys by mapping them to the special `<Nop>` target:
:inoremap <BS> <Nop>
:inoremap <Del> <Nop>
(Assuming you only want them disabled in insert mode.)
Problem
I'd like to use Vim for distraction-free writing instead of PyRoom/TextRoom. This post, which mentions VimRoom, could already show me how to get most settings. I only miss how to enable TextRoom style flow mode: How can I disable backspace and delete keys (not shortcuts like d$)?
