Where is the Desktop Editors main 'help' page?

I ended up on a Desktop Editors webpage I’ve never seen before that seemed to include links to all features.

I don’t know how I got there and now that I’m not there I don’t know how to get there again.

Where to?

Hello,
There is the following page with guides dedicated to Desktop Editor -

There is also this page describing Editor’s different features - UserGuides - Docs ONLYOFFICE Document Editor - ONLYOFFICE (most of the features relevant for Docs are also relevant for Desktop Editor)

If these pages are not the ones you were looking for, please describe the content of the needed page in more detail
