Version (which release did you use?)
master

Describe the bug
Right Alt does not work for keybindings that use Alt as a modifier.

To Reproduce
With the default config
Press Right Ctrl + Right Alt + W to try to activate work mode

Expected behavior
Activate work mode

Actual behavior
Work mode is not activated

This is actually by design to support some keyboard layouts that use the AltGr key (#210)

However, you can configure nog to use the right alt key by adding this to your config

nog.config.allow_right_alt = true

It looks like this was accidentally omitted from the documentation rewrite. I'll check in an update to that later today.
