How to change tab size on GitHub?

Question

When I view files on GitHub, tabs appear as 8 spaces.

Example:

Is that possible to change this configuration to 2 or 4 spaces?

Answer 1

You can append ?ts=2 or ?ts=4 to the URL to change the tab-size.

Example: https://github.com/jquery/jquery/blob/master/src/core.js?ts=2

It seems that the value can be anything from 1 to 12. It does not work on Gists or raw file views though.
