We all usually go to a solution or the customization area to see the entity metadata, may it be attributes or properties related to the entity like auditing etc.
There are also tools that a lot of developers use like the Entity metadata browser, which is a solution that you install in your environment and can browse through the metadata in an easier manner.
What I find most productive is to query the metadata from the browser itself by forming the URL specific to the entity I am looking for.
