Wrong documentation
What article/section is this about?
Most articles that refer to using the action menus available from content/media/member trees.
The best way to find them is to search for the term 'right click' in the V14 docs

eg here we've updated the document screenshots:
https://docs.umbraco.com/umbraco-cms/fundamentals/data/members#creating-a-member
but kept the V13 instruction in the text to be 'Go to the Settings section, right-click Member Types and select Create.'
Describe the issue
With Umbraco 14 - we've removed the ability for editors and implementers to right click items listed in the current tree (quite rightly! - umbraco/Umbraco-CMS#16233) to perform actions or open context menus, but in the documentation for V14, when explaining how Umbraco works, we still use language which instructs people to right click, and we need to tell people about using the ... and + icons instead.
