3: ' → №; 4: * → %

My Mac keyboard:

Number | Latin | Cyrillic | Cyrillic here
-------| ----- | ---------|--------------
`3`    | `#`   | `№`      | `'` 
`4`    | `$`   | `%`      | `*`

I'm not sure whether all Russian mac keyboards are like this, and whether it's more useful than `'` and `*`. Creating this pull request to start a discussion.
