You pseudo code pretty much has all the elements you need - there is a
variable called major-mode which you can use to do something based on
the mode you are in. However, I would suggest you check out using mode
hooks instead. Nearly all modes have a 'hook' you can set to do things
in a mode when it is loaded - this is the normal place to put mode
specific customizations. Many modes have multiple hooks that are run
at different times e.g. before loading the mode code, after loadinig
it etc.
