Sounds like the bottom line is you want clicks to pass to the other windows as well/instead of keypresses. Unfortunately I personally have no clue whether there's a program that passes clicks correctly on a single comp(I know there's some that can pass to multiple computers though lol) so we'll see if someone else knows =\

(Clicking a is bad baaaaad habit though, break it while you can, you'll not regret it in favor of keypresses ;) )
