Grouping hosts in SSH Config

Question

Can I configure the hosts in my SSH config by groups? For example, I'd like to set a single same user to be used for one group of hosts and another one for another group of hosts.

If it's not possible out of the box, I guess there might be tools that can write or manage your ssh_config through a config file format with some richer options?

You should take a look at man 5 ssh_config for all the details on this, but yes, you can do that by doing this in your ~/ssh_config:

Host srv1 srv2 srv3
    User jorn

Host srv4 srv5 srv6
    User jornv
