Google Spreadsheets URL Syntax and Display Options?

Question

I recently came across a Google Spreadsheet that had a slightly different syntax in the URL. I found these tags after the Spreadsheet Key:

&single=true&gid=0&range=B5%3AB5&output=html

My question is what are these and where do I find a list of all the options???

I experimented by putting each of these at the end of one of my docs and discovered some things changed as a result:

&single=true

&gid=0

&range=B5%3AB5

&output=html

I was particularly interested in &range=
When I chose a regular range such as A1:B2 it also worked

But why &range=B5%3AB5 What does it mean and how do I use it?

Does anyone have documentation about what other display options exist?

Answer 1

This link has a few of the ones you mentioned and some you didn't

Reference Guide - Google Spreadsheets API - Google Code

some of the page is irrelevant to the question.

Answer 2

The special characters are encoded using URL encoding. If you have to use special characters in the URL, you will need to encode them. You can use a web app such as this for doing the same.
