When you press F5, st encodes it as the sequence ^[[15~, where ^[ indicates the
escape key. If that sequence isn't mapped to something in vim, then vim
interprets it just as if you'd typed those keys by hand. So ^[[15~ corresponds
to 1) hitting escape 2) running the command `[1`, which is invalid and does
nothing 3) running the command `5~`, which toggles the case of the next 5
characters.
The issue is most likely a problem with $TERM. Vim doesn't know that ^[[15~
means F5 without being told. That's the purpose of $TERM and terminfo, to tell
vim that when it sees ^[[15~, that's the terminal sending F5.
So you need to 1) ensure that TERM=st-256color, 2) ensure that st-256color
exists in /usr/share/terminfo/s/st256-color or in ~/.terminfo. If you use ssh,
they must be on the machines you ssh into as well.
If you run `infocmp` and the output says st-256color and kf5=\E[15~, then your
terminfo is good. Also `:set termcap` inside vim should show the same thing for
t_k5, and `:map` should show <F5> bound to something.
Setting TERM=xterm happens to work but it's not proper. It's telling programs
that st speaks the same control sequences as xterm, which is not quite correct.
