This app fetches commands and shortcuts for some apps, and shows them. Caching full support. I will update apps list periodically, and apk update won't be needed.
If you want to see more apps, please write me http://t.me/twi1ight_spark1e or right here in reviews.
Also there is a GIT repository of this app! https://middev.ru/gogs/Twilight_Sparkle/UniversalCheatsheet
