Miscellaneous Needful things

I found this article discussions.apple.com/thread/2104245
and installed WordService. However the functions shown on the drop-down menu are quite limited:

775×283

How may I convert the case of some selected texts with WordService? Thank you.

System Preferences > Keyboard > Keyboard Shortcuts > Services < Text.

Turn on the ones you want.
