Configuring port forwarding in config for ssh

I often run ssh forwarding ports. I also make use of config files quite often for this job.

I often run the following command to do this:

ssh -L 3128:localhost:3128 www.example.com -l username

However, the syntax in the ssh config file is not quite what you would expect and differs depending on whether its an inbound or outbound forwarding. The following is the config for local forwarding

Host example_proxy
 User username
 Hostname www.example.com
 IdentityFile /home/user/.ssh/pwdlogin
 Compression yes
 CompressionLevel 7
 Cipher blowfish
 LocalForward 3128 localhost:3128

Notice the awkardly placed spelling. No-one in the man file is this explained. Admittedly its not much of a leap of faith to work out that -L is LocalForward and -R is RemoteForward but seriously this could be in the man file.
