如何让活动应用程序浮动到启动器的顶部

Alt当使用+或单击启动器上该窗口的图标切换到窗口时，如何使启动器上的图标跳转到启动器的顶部Tab ？

答案1

介绍

下面的脚本使当前活动窗口的图标浮动到启动器的顶部。它可以手动运行，也可以作为启动应用程序的一部分来启动用户会话。

设置

用户可以从这里复制脚本源，或者通过以下方式获取脚本的副本git：

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

脚本文件是/opt/sergrep/float_active_app.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/float_active_app.sh（完整路径）作为命令
