@jeffcao Write these into .vimrc:

set keyprotocol=
let &term=&term

I did. but when i run cmd 'vi aa.txt' , below error msg show:

Error detected while processing /usr/share/vim/vimrc[53]../etc/vim/vimrc.local:
line    1:
E518: Unknown option: keyprotocol=
Press ENTER or type command to continue

@jeffcao

vi ~/.vimrc
It doesn't matter if .vimrc doesn't exist.

or use this

echo 'set keyprotocol=' >> ~/.vimrc
echo 'let &term=&term' >> ~/.vimrc

I tried again, and there was no such problem. What's your version of vim?

The ESC [?4m control sequence (XTQMODKEYS , Query key modifier options) was introduced in vim 9.0. WindTerm 2.7.0 Prerelease 2 now supports parsing ESC [?4m. Please download and try it. Thank you.
