linux窗口切换快捷键

We’ve already shown you how to customize shortcut keys in any Linux application, but for today’s lesson we’ll take it a step beyond—and assign a shortcut key that switches an open application to be the currently focused window.

我们已经向您展示了如何在任何Linux应用程序中自定义快捷键 ，但是在今天的课程中，我们将进一步介绍它，并指定将打开的应用程序切换为当前焦点窗口的快捷键。

The idea is that instead of using the mouse or flipping through a set of windows in the Alt+Tab switcher, you can quickly assign a hotkey to your most important windows and switch to them with a single keystroke, saving yourself a lot of time. To accomplish this task on Linux, we’ll use the excellent AutoKey utility.

这个想法是，您无需使用鼠标或在Alt + Tab切换器中浏览一组窗口，而是可以将热键快速分配给最重要的窗口，并通过一次按键即可切换到它们，从而节省了很多时间。 为了在Linux上完成此任务，我们将使用出色的AutoKey实用程序。

Note: if you want the Windows way to do this, you can accomplish the task with AutoHotkey easily.

注意：如果您希望使用Windows的方式来执行此操作，则可以使用AutoHotkey轻松完成任务 。

场景 (The Scenario)

Since I do most of my work in Google Chrome, I need to have it accessible as quickly as possible and I generally assign the Alt+G key combination to switch to my open Chrome window.

由于我的大部分工作都是在Google Chrome浏览器中完成的，因此我需要尽快对其进行访问，并且通常会分配Alt + G组合键切换到打开的Chrome窗口。

安装自动密钥 (Installing AutoKey)

You’ll want to open up the Synaptic Package Manager and do a quick search for autokey, check the box, and then install the package. You could also install it using the apt-get command like this:

您将要打开Synaptic软件包管理器并快速搜索autokey ，选中该复选框，然后安装该软件包。 您也可以使用apt-get命令安装它，如下所示：

sudo apt-get install autokey

sudo apt-get install autokey

将快捷键分配给应用程序窗口 (Assigning a Shortcut Key to an Application Window)

Open up the AutoKey configuration screen from the system tray icon, and then create a New Script from the menu, and then paste in the following code:

从系统任务栏图标打开“自动键配置”屏幕，然后从菜单中创建“新脚本”，然后粘贴以下代码：

window.activate(‘Google Chrome’)

window.activate('Google Chrome')

You’ll want to use the Set button next to the Hotkey setting, and assign your preferred hotkey—mine is Alt+G, though you’ll want to make sure that you use a lowercase g while setting the hotkey—if you set it using an uppercase letter it won’t behave right.

您将要使用“热键”设置旁边的“设置”按钮，并分配您首选的热键(我的是Alt + G，尽管要确保在设置热键时使用小写的g)(如果设置了该键)使用大写字母将无法正常工作。

Once you save the setting and minimize or close the AutoKey configuration screen, you can hit the Alt+G shortcut key combination anytime you want to switch to the open window.

保存设置并最小化或关闭“自动键”配置屏幕后，您随时可以切换到打开的窗口，按Alt + G快捷键组合。

这是如何运作的？ (How Does This Work?)

When you hit the shortcut key that you’ve assigned, AutoKey will run the script that you’ve added—in this case, it’s a simple Python script that uses the wmctrl functions to control open windows. Here’s the syntax for the window.activate function, which switches the specified window to be the active window:

当您按下分配的快捷键时，AutoKey将运行您添加的脚本-在这种情况下，这是一个简单的Python脚本，使用wmctrl函数控制打开的窗口。 这是window.activate函数的语法，该函数将指定的窗口切换为活动窗口：

window.activate(‘partial window title here’)

window.activate('部分窗口标题在这里')

Basically all you need to do is match part of the window title, and in the case of Google Chrome, the window title always has “- Google Chrome” at the end.

基本上，您需要做的就是匹配窗口标题的一部分，对于Google Chrome，窗口标题的末尾总是带有“-Google Chrome”。
