咖啡因印度人的键盘快捷键

有什么方法可以设置键盘快捷键吗caffeine-indicator？或者我可以从终端运行的命令。我正在使用 Ubuntu 16.04 LTS。Caffeine Indicator v2.8.3。

答案1

我知道这是一个非常老的问题，但也许这会对某些人有所帮助。

事实证明，caffeine-indicator 只是一个位于 /usr/bin/caffeine-indicator 的 python 脚本。我编辑了该脚本以允许切换键盘快捷键。当前设置为 ctrl + t，但您可以通过更改代码中的快捷键字符串将其编辑为任何您想要的。请注意，特殊键必须用 <> 括起来，而普通键（如 t）则不能。这是编辑后的脚本：
