当你使用 Mac OS X 系统自带当输入法，在键盘按住元音字符时（如字符 A），

会弹出与字符 A 相似的框供选择，如果是非元音字符，也未出现重复的按键字符：

元音字符：

非元音字符：

其实在 Mac OS X 系统早期版本中，引入了按键开关，我们可以通过如下方式改变默认按键的行为：

Disable Popup / Enable Key Repeat

$ defaults write -g ApplePressAndHoldEnabled -bool false

Enable Popup / Disable Key Repeat

$ defaults write -g ApplePressAndHoldEnabled -bool true

以上配置是全局的，如果你想未某个软件独立设置，参考如下：

Sublime

$ defaults write com.sublimetext.3 ApplePressAndHoldEnabled -bool false

VSCODE

To disable the Apple press and hold for VSCode only, run this command in a terminal:

$ defaults write com.microsoft.VSCode ApplePressAndHoldEnabled -bool false

To re-enable, run this command in a terminal:

$ defaults write com.microsoft.VSCode ApplePressAndHoldEnabled -bool true

注: 此设置变更需要重启应用；
