如果你正在使用 HTML 编写展示终端软件，可以使用特殊的 JavaScript 函数来控制屏幕键盘。

使用 JavaScript，你可以显示、隐藏或移动键盘。只需使用特殊的 JavaScript 函数将与键盘相关的信息添加到浏览器标题中，应用程序将监视标题的更改。

WM_CSKEYBOARDMOVE：解决在使用不同 DPI 的多个屏幕时移动键盘的问题。

例如，屏幕 1 的分辨率为 2560x1440，在 Windows 显示设置中设置为 "125% 缩放"。屏幕 2 的分辨率为 1920x1080，设置为 "100% 缩放"。

打开 CKeys.exe 文件的 Windows 10 应用兼容性设置，并将 DPI 行为设置为"Application"，这意味着应用程序管理所有与 DPI 相关的计算。启用此设置后，您可以将物理像素值传递给 API 的移动函数，键盘窗口将准确移动到该位置。

如果你想以编程方式激活此兼容模式（例如，通过你自己的安装程序），你需要设置以下注册表键：

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers:

"C:\Program Files\ComfortKeys\CKeys.exe"="~ HIGHDPIAWARE"

这将适用于所有用户。或者，你可以将此项放在当前用户的注册表中 (HKCU)。
