I do the same with with my MBP and iPad. It facilitates muscle memory. 
I don’t use it at all so it is on hide and at the bottom. I see it sometimes by mistake as it were.
I am going minimalist on my IT at the moment, let’s see how long it lasts. That means stepping up keyboard shortcuts. I think the dock is only accessible by clicking on it? or did I get that wrong too?
On the left, autohide.
My current setup is four displays, 27", 23", 20", and 7". I’ve Keyboard Maestro setup so that Hyper - Arrow Key moves the pointer to a specific display. Thus Hyper - Left Arrow moves it to the leftmost display, within easy reach of the dock.
I also use uBar, (bottom, autohide), as I wanted a ‘dock’ on each monitor. uBar has it’s quirks but overall I’m happy with it.
Hey Andy,
Get idea for using hot corners. What app did you use to set that up?
BetterTouchTool. It’s a super app for productivity.
