Nemo

I am using the cloud services at CSC and they do not allow ssh login with the traditional login/password combo.
When I want to make a bookmark in my file manager (Nemo) pointing to this location. I need to specify a rsa key file. that is used for the login. On the command line, it looks as follows:

ssh -i ~/.ssh/encypted_rsa_key.pem cloud-user@pouta
