I have an extremely large model for which I need a way to (First:) automatically identify and select any transformers that are connected to a writer that I already have selected. (Second:), I need a way to "Switch the Selection" so that everything else gets selected. Once I'm at that point, I can choose to disable those selected objects. Then I run my model to publish ONLY my original selected feature type.

Hi @steveg374 - What a cool idea! I'm wondering if you are using FME 2016.1 or Newer? There is a new "transformer" called Junction. You can right-click the Output Port of the Reader and select "Insert Junction" – then you will only have to disable the one Junction object, instead of worrying to select items downstream.
Now, this may not exactly address your concern but I hope it helps!
(Note: After reading over your posting again – did I misinterpret? Did you want to select the Reader, the first lot of transformers, but disable everything else?)

I'm using FME 2017. I didn't know about the Junction transformer, and I can see how it's useful; but unfortunately I don't think it helps me with this particular problem. I'll try and explain it a little better:
My main model has well over 200 Readers, 200 Writers, and over 3000 Transformers. As it stands now, if I only needed to re-publish 1 specific Writer and I don't have time to wait for the entire model to run (which takes 2.5 hours), then I have to (1) select every object in my model, (2) spend a lot of time backtracking (from the Writer that I want to re-publish) in my model to determine which specific 'upstream' Readers AND Transformers contribute to the Writer that I need to re-publish - and unselect those as I encounter each one, (3) Disable everything that remains selected, and (4) run the model and hope that I didn't miss something.
So...in my mind, here are the steps that I would take if I could: (1) select only the Writer(s) that I need to re-publish, (2) ask FME to select any/all 'upstream' Transformers AND Readers that contribute to re-publishing my selected Writer(s), and (3) disable every other object that doesn't get selected by my step #2 above, (4) then run the model.

@steveg374 - Thank you for providing a deeper illustration! I can't think of a good way to get around this right now.. I can see your argument for support of selecting everything upstream (or downstream) of a particular point.
Sorry I do't have a solution but just wanted to add that, I love this idea! Being able to right-click a reader, writer or transformer and selecting connected objects upstream, downstream or both would be great.I quite often want to select and copy out parts of a workbench for troubleshooting or to re-purpose for a new workbench and sometimes it can take a while to select just the objects and connections I need.
