Command line attributes

Hi,

Is there any document describing what properties can be changed using command line?

For example, in mailmate I had these:

alias _mmatenext_up='defaults write com.freron.MailMate MmMessagesOutlineMoveStrategy -string "next"'
alias _mmateprevious_down='defaults write com.freron.MailMate MmMessagesOutlineMoveStrategy -string "previous"'

Thanks.

Best regards,
Marc
