程序运行时禁用密钥

重复问题如何在特定程序运行时禁用密钥？ ，从未回答过。 （哪个选项更糟糕的是，我重新发布了同样的问题，或者我将旧post发送给死者？）

无论如何，有没有办法在特定程序运行时禁用特定键？ 或者，在特定程序运行时禁用Dash？

Answer 1

简单解决方案

创建两个快捷方式，一个用于禁用超级密钥，另一个用于随意恢复。

转到系统设置 – >键盘 – >快捷方式 – >自定义，然后单击+按钮。 将新快捷方式命名为“Disable Dash”。 命令是

gsettings set org.compiz.unityshell:/org/compiz/profiles/unity/plugins/unityshell/ show-launcher 'Disabled' 

要创建重新启用脚本的快捷方式，请重复上述步骤，但命令应该是

  gsettings set org.compiz.unityshell:/org/compiz/profiles/unity/plugins/unityshell/ show-launcher '' 

脚本解决方案

当用户指定的程序具有焦点时，下面的脚本将禁用超级键。 请注意，用户仍然可以使用鼠标单击短划线图标来调用Dash。 程序名称必须是单引号，并且与Unity Launcher中显示的完全相同。 可以使用以空格分隔的相同格式指定多个窗口

例如，要在每次firefox窗口都有焦点时禁用超级密钥，必须将脚本调用为

 disable_super_key.sh 'Firefox Web Browser' 

要同时禁用firefox和gnome-terminal

 disable_super_key.sh 'Firefox Web Browser' 'Terminal' 

如何获取脚本

用户可以在此处复制源代码，也可以按照以下说明从github获取源代码：

1. sudo apt-get install git
2. cd /opt ; sudo git clone https://github.com/SergKolo/sergrep.git
3. sudo chmod -R +x sergrep

该脚本将位于/opt/sergrep/disable_super_key.sh

要使脚本在每次登录时自动启动，请参阅如何在登录时自动启动应用程序？ 。 提供/opt/sergrep/disable_super_key.sh （完整路径）作为命令
