Git: Alias for multiple Github accounts in SSH

Say you have two github accounts. So you have different SSH keys. Github won't know which key relates to which account.
 
However, in your ~/.ssh/config file you can setup an alias that uses the correct IndentityFile to send to github.
 
In that file, put this:

Host new_alias
        Hostname github.com
        User git
        IdentityFile ~/.ssh/id_rsa_new_identity

Now you can use git remote origin git@new_alias:your_username/therepo.git Note the : after the alias name. And the fact you're putting git@ at the start.
