To make sure, that means basically the same thing as the following 
pseudocode?

  if (key1 or key2 and (key3 and not key 4))

And the parentheses around the second pair is optional, but there to 
guarantee the precedence?

And, we can optionally include whitespace to make the condition read better?

   #IF(key1 | key2 & (key3 & !key4))

If so, then thumbs up.

Thumbs up.

I prefer the ending colon, because it makes it very clear where the 
actual line text begins. But, it's not hugely important.
