I'm having some problems remapping my home key; it works when I run Vim from tmux but not when I run it from a regular xterm without tmux. It looks like they're sending different escape codes and Vim only picks up on tmux's one for some reason.
I tried mucking about with a lot of
TERM values, to no avail. So I figured I'd just hard-code this escape code in my vimrc and move on:
set nocompatible " `^[` is the escape character. set <Home>=^[OH set t_kh=^[OH echo &t_kh noremap <Home> :echoerr "home!"<CR>
$ vim -u vimrc Vim outputs
^[OH, which is expected. But after I've started Vim the setting seems to be not set:
:set t_kh? E846: Key code not set: t_kh? :verbose set t_kh? E846: Key code not set: t_kh?
And the remapped home key doesn't work. Manually running
:set <Home> or
:set t_kh fixes the problem; I can now use my custom
Why aren't these options taking effect? How can I make them take effect?
I have no plugins and am using Vim 8.0.586 on Arch Linux.
