对于那些使用VS Code Insiders的人来说，只需将Bundle标识符更改为:

defaults write com.microsoft.VSCodeInsiders ApplePressAndHoldEnabled -bool false

你在OSX上，对吗?如果是这样的话，问题可能出在苹果的“按住键”(Press&Hold)上，你可以在长按时选择其他字符。

你可以在终端中使用defaults命令禁用这个“特性”:

defaults write NSGlobalDomain ApplePressAndHoldEnabled -bool false

之后你必须重新启动VSCode。

要重新启用先前的行为:

defaults write NSGlobalDomain ApplePressAndHoldEnabled -bool true

史蒂夫的最佳答案并不适用于我的mac '默认写com.microsoft.VSCode ApplePressAndHoldEnabled -bool false'，但下面对我有用:

sudo defaults write -g ApplePressAndHoldEnabled -bool false

参考:https://github.com/VSCodeVim/Vim/issues/345

Though I reset with above mentioned commands and even after reboot, Once I open
VSCode they are getting reset, so I had 'code' script to set them back
every time I open VSCode editor.

 $ cat code
VSCODE_CWD="$PWD" open -n -b "com.microsoft.VSCode" --args $* &
defaults write com.microsoft.VSCode ApplePressAndHoldEnabled -bool false
defaults delete -g ApplePressAndHoldEnabled

VS Code的官方vim-plugin提到了如何在macOS上设置它

defaults write com.microsoft.VSCode ApplePressAndHoldEnabled -bool false
defaults delete -g ApplePressAndHoldEnabled  # If necessary, reset global default

如果你在Mac M1上，我必须做的是运行@NoAppleOnHead说的:

sudo defaults write -g ApplePressAndHoldEnabled -bool false

然后重新启动你的Mac，你应该很好
