No genuine ones. There are some extremely few ones, but they&#x27;re all related to &quot;some people use emacs and it&#x27;s good for you to fit in with them&quot; (for instance, I recall a proof assistant some years ago which was painful to use without the associated emacs mode).<p>Any advantage gained from the interface are small enough that they&#x27;re not worth introducing another mental mode for. Any time you sit down at a keyboard and have to mentally remap (&quot;copy works differently here&quot;, &quot;shortcuts are different here&quot;, &quot;that thing you do all the time must be done in a very different way here&quot;), it&#x27;s mental capacity out the window. When you do a task, you want your interface to be as similar as possible to the interfaces you&#x27;re used to when doing related tasks.<p>Emacs <i>could</i> have become the common, core interface for working on a computer (unlike vi, I&#x27;d say) - but it didn&#x27;t. The common user access standards that you&#x27;re used to in VS, Eclipse and IDEA did. Spend your time mastering those instead, it will give far more transferable and valuable skills.
