Reusable content in entries, globals? How do I use/call globals in entries? Trying to insert a simple global called {{ whateveryounameit }} with some text but don't see anything except its name.

Any other ways to display common content across multiple entries?
You call globals with the globals' handle, and the field name of a field in it. So, if you have a text input field named "myField" inside a global with handle "myGlobal", you can call it anywhere in your templates with:

{{ myGlobal.myField }}
