Embedding Google Docs
Google Docs URL Parameters
I am not aware of any official documentation of the various parameters/arguments that can be used in conjunction with Google Docs URLs, but I have found an unofficial list here.
I have tried some of these in some of the tips I have given. But as they are not 'official' they may or may not continue to work. I have copied the list from that page below so it may be worth checking the source to see if any others have been added.
Example of usage
If you want to provide a link to a Google Doc and force a copy to be made rather than have it just open then use the /copy suffix.
Some parameters are only appropriate for certain doctypes - e.g &range= would only make sense for a spreadsheet
