Learn keyboard shortcuts

Knowing keyboard shortcuts is a game-changer. Not just for programmers, but for anyone working on a laptop. Of course, I'd expect everyone to be comfortable with Ctrl + C for copy and Ctrl + V for paste, but I've been investing in learning some others too:

1. Ctrl + backspace - Deleted the whole word. Sometimes its easier to start from scratch, rather than fix that one typo at col 4. This is actually a meta point - often it is easier to start something from scratch rather than fix the existing thing - immediate mode graphical user interfaces apply this principle.
2. Alt + Tab - this should really be number 1. I use this all the time to quickly swap between windows. Handy when writing code and swapping to the terminal or documentation… or ChatGPT ;)
3. Ctrl + t - new tab in the browser

I'm sure there are so many more I use without even thinking but these three get you the 80% of result with 20% of the effort. Would highly recommend committing a week to really get these down as second nature.
