Trying to learn on the go

I'm trying to learn gdscript so I can get a better handle on what I'm doing on a tutorial build. Website I'm using feels like it has been helping a lot, but I can't use the phones keyboard on its programming yourself parts. Any recommendations for how I can practice and learn while I'm not on my home pc?

Phone is Galaxy Z Fold5 Website I've been learning with: https://gdquest.github.io/learn-gdscript/?ref=godot-docs#course/lesson-2-your-first-error/practice-85733.tres
