Eliminating vim ESC key delay

After upgrade my mac to high sierra, I figured out that there’s little delay for after ESC key in vim.

I usually use vim for development and blogging, so it’s quite a big problem.

After googling, I found solution for this.

In vim config

• ~/.vimrc or your vim config, add this line

set timeoutlen=1000 ttimeoutlen=0

• timeoutlen is used for mapping delays, and ttimeoutlen is used for key code delays.
• You can check docs here

After add timeoutlen settings, the problem perfectly gone!

In addition to this solution, there’s more for zsh and tmux users.

In your zsh setting, add (~/.zshrc)

# 10ms for key sequences in zsh
KEYTIMEOUT=1

And also in your tmux setting, (~/.tmux.conf)

set -s escape-time 0

It’s from stackexchange answer Also don’t forget tmux source-file ~/.tmux.conf for appling.
