If you're a programmer who uses the mouse a lot and is suddenly WFH, now seems to me like a perfect time to invest in upskilling on keyboard-first work. You'll be a little slower to start with (while no one's watching!) but long-term your productivity will increase significantly.
How to start? Simply set a timer for 5 minutes and commit to not touching your mouse for that time. You'd better learn to manipulate your browser with shortcuts so you can google other shortcuts! Slowly increase the time by 5 minutes.
You may want to print out your IDE's shortcuts reference card, or even better, many IDEs have a "search for action" shortcut you can use to find stuff. When you find it, DON'T hit enter on the action you want. Instead, note the shortcut, exit the search and use the shortcut.
There *are* tasks which are more quickly done with a mouse than with the keyboard, but they are much fewer than most people believe. If you regularly use the mouse to select text, that's a sure sign that you can speed up with some easy shortcuts. Good luck!
