Focus maybe on some CLI tools, like text editor. I use Vim, it was pain to learn but been worth it, since you don’t have to leave the keyboard for anything. Once you learn the layout you can use it in other IDEs that also, many have plugins or built in support for Vim layout (JetBrains IDEs do) so I can use the same key map in desktop apps to do C# and C++, etc…
Also use Vim Mode that mode in the https://obsidian.md/. Which is great since you can also use Vim in the CLI to edit the Markdown Files.
Good Vim Cheat Sheet, bit confusing but as you get use to VIM it makes more sense.

Also this book is pretty handy, the 3rd edition dropped GUI apps and focuses 100% on CLI.

Handy if you have a Steam Deck also.
Went to Fedora on Pro gen 1, works great. Pen input in Krita works great. Really miss the form factor of that first gen. I feel like they’re too big now.
