&gt; <i>Finally I&#x27;m never going to buy the efficiency of keyboard shortcuts when coding is generally worth the time sink in learning them over clicking a mouse in an IDE.</i><p>So here&#x27;s your problem, right. I&#x27;m not <i>selling</i> this to you. If I were stating it, I&#x27;d be stating it as a fact. <i>Most</i> of HN would agree with it because they themselves experienced it. Indeed the only ones who would disagree with it are the ones &quot;not buying it&quot;.<p>Try it if you want, I don&#x27;t really care if you don&#x27;t, but you&#x27;re making assumptions and reacting to this with <i>fear</i> instead of <i>curiosity</i>. And that, above <i>anything</i> else, is something that will make you less efficient not just in your work but in your entire life - so you&#x27;re in a pretty bad spot to lecture others on efficiency...
