Today, enjoying a day off and browsing around Twitter to get upset about nothing, I found something to get slightly excited about. I don't have the patience to find the tweet now, but it was very much along the lines that being able to do most things as a software developer without touching your mouse is an important goal. So, the act of navigating your development environment, going about daily tasks, without using your mouse. That's something to get excited about, for sure.
First of all, no, go use your mouse, or trackpad, or whatever pointing device you're computer has attached. Or don't. Or use IntelliJ or VS Code or Emacs or VI or whatever really does it for you. Or use notepad. Or nano. Don't do what slows you down, do what makes you fast. You, not anyone else. Don't listen to random folks on the internet that try to establish a connection between a nuanced mastery of some skill and eventual success in your trade. Correlation does not equal causation.
But to bring the bigger point home - being able to write code fast is useful, it's a good skill to have. Not having to try to find the right keys on the keyboard, not making too many typing mistakes definitely speeds up the act of "code creation", but with all the advances in AI and LLMs, the question is also for how long that's actually going to be relevant. But if you're a software engineer, only a fraction of your time is actually spent coding. Reading code, investigating bugs, documenting things, discussions, understanding problems and defining solutions, all of those are highly relevant activities. And true, some of them can be completed in your development environment, for the most part: Good luck solving them not touching the mouse.
Your job as a software engineer - or software developer, if that's the first line on your CV, is in fact not to write code, it's to make problems go away. Writing code is one of the many ways in which this can be accomplished, but it's really only one. I've seen people do crazy things when developing, from typing speed to mastery of a single environment, and yet they've never really grown beyond being keyboard cowboys - there's no extra points for being incredibly good at one thing and ignorant of all the rest. And a person being average at all the things that define a well-rounded software engineer will blow someone being incredibly good at one thing out of the water any day.
So, before learning to ignore a key input device for internet points, learn something that's actually relevant in your career - do a course on rhetoric, learn how to write well or join a discussion club. All of that will make a much more significant difference in how you'll progress as an engineer than your mastery of an IDE.
