&gt; 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.<p>That&#x27;s true, which is why I use only Linux, only StumpWM, only emacs.  Using anything else slows me down and gets in my way.<p>&gt; 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.<p>There&#x27;s nothing to master, because the languages those tools offer aren&#x27;t expressive enough to require any mastering.  They&#x27;re two steps above pointing and grunting, while emacs is poetry.
