两周以来，我一直在 LaTeX 中搜索 LMB（鼠标左键单击）或 RMB（鼠标右键单击）符号。我曾在手册中看到过它，但现在再也找不到它了……
现在我想编写一本手册，为了更容易理解如何使用该软件，集成这些简单的符号就太好了！
我已经在 Illustrator 中设计了符号。但现在我不知道如何将其导入 LaTeX 或如何使用“特殊”包来设计符号？！？
缺少图片，因为我是新手，不允许上传图片。
它应该看起来像一个椭圆形。顶部的椭圆形中有一个倒置的 T。如果它应该是“鼠标左键单击”，则左侧是黑色。如果它应该是“鼠标右键单击”，则右侧是黑色。
希望描述足够充分。如果不够，请发帖，我会将图片发给您。
答案1
由于您已经创建了这些图像，因此只需将它们包含在文档中即可。确保图像周围的边界框紧密，否则图像周围会出现太多空白。
要包含图像，请使用
\usepackage{graphicx}% http://ctan.org/pkg/graphicx
在文档序言中，以及类似命令
\newcommand{\LMB}{\includegraphics[height=.8\baselineskip]{LMB}}% Left Mouse Button
\newcommand{\RMB}{\includegraphics[height=.8\baselineskip]{RMB}}% Right Mouse Button
您的按钮从 Adobe Illustrator 导出为LMB.pdf和RMB.pdf（如果您使用 PDFLaTeX）。
上述命令允许您在文本中使用\LMB和\RMB，并以基线高度的 80% 打印图像。根据您的使用情况，您可能还想包括xspace包裹并在每个命令后插入。这样可以简化/\xspace的使用，而不必总是在它后面添加控制空格。\LMB\RMB\

我通过谷歌来到这里，希望这个页面会被啮齿动物占领，结果我失望了……但下一个谷歌用户不必忍受这样的失望。即使他们寻求更尖锐的种类。
文档嵌入在代码中，这是从我维护的供个人使用的包中复制/粘贴的。所有部分\begin/end{macrocode}都被剥离了，但它不必要地创建了一个compeng系列/名称空间。虽然这不应该惹恼最终用户。如果对该包感兴趣，请告诉我，我可以在稍微清理文件后将其发布到 CTAN 上，它主要包含用于 GUI 和文档的图标。
