Remove delay after pressing Esc key

[Hubro]

General information

Basic examination

• I have read through the README page
• I have the latest version of zsh-vi-mode
• I have tested with another terminal program (Gnome Terminal)

Problem description

After pressing Esc, there is a short delay before ZVM enters Normal mode.

1. Press down Esc key
2. Release Esc key
3. ~200 ms
4. Normal mode

This means that very often when I press: EsckEnter in order to run the previous command, nothing happens. If I intentionally do it slowly, it works, but this is a key combination I press very, very often, so I naturally do it really fast.

Reproduction steps

Read above

Expected behavior

Ideally ZVM would enter Normal mode immediately when the Esc key is pressed down, with no delay.

To compare, I have tried:

• vim/nvim in the terminal
• Bash built-in vi-mode
• ZSH built-in vi-mode

None of the above have any perceivable delay after pressing Esc. I can press EsckEnter as fast as I possibly can, and they never miss any of the keystrokes.

Hi @Hubro

Thanks for the reporting, could your provide me your dotfiles (e.g. .zshrc) and keybindings (i.e. typing this command bindkey -M viins | grep '"\^\[' in your term)? I will try to help you solve this issue as soon as possible.

Thanks and regards

Hi @Hubro

This issue has been addressed and fixed. Please update to the latest version and try again.

Thanks and regards

[Hubro]

@jeffreytse Awesome! The delay is still there, but now my keystrokes are never lost. They are just slightly delayed. That's a massive improvement 😄

@jeffreytse Hi, I am using blinking beam as insert mode cursor style and blinking block as normal mode cursor style. When I switch from insert mode to normal mode, I noticed there is a little delay between when I press ESC key and when the cursor becomes to blinking block. But when I switch from normal mode to insert mode, the cursor becomes to blinking beam instantly. I searched this problem on the internet and find this question.
Is there any solution that can switch the cursor style from insert mode to normal mode instantly? Thank you very much.

Hi @Alex-duzhichao

Thanks for your question, can you provide me some more details such as a video record for this behavior, your environment info and so on.

Thanks & Regards

Hi @jeffreytse
Thank you for you reply. After some test, I find the npm plugin in ohmyzsh is the reason causes the delay. After uninstall the npm plugin, the delay disappears.
Thank you for your help again.

Hi @Alex-duzhichao

It's glad to hear your good news. Welcome to star this project for further update in the future.
And hope you have a good day! : )

Thank you for you reply. After some test, I find the npm plugin in ohmyzsh is the reason causes the delay. After uninstall the npm plugin, the delay disappears.

I had the exact same issue with the exact same plugin. I don't think it's really the plugin's fault, but NVM itself. When you source the NVM script it takes a second or two for some reason. I worked around the issue by installing NVM through my package manager and sourcing it myself with the --no-use flag, which avoids the startup delay.

NVM_INIT_SCRIPT="/usr/share/nvm/init-nvm.sh"
if [[ -f "$NVM_INIT_SCRIPT" ]]; then
    source "$NVM_INIT_SCRIPT" --no-use
