And I've always wondered why Safari's menu shows ⌘+ for "Zoom In" when ⌘= works just fine...totally unintuitive.
Actually I suspect that's how it works.
think about screen capture. shift-cmd-3. by the above they could have instead said cmd-#
the 3 (or in your case the =) refers to the key on the keyboard, not the character it produces. If it's shifted, it's still the 3 or the = key. the shift must be stated explicitly, and so the key is stated as un-shifted.
Though it's interesting to note that in that specific instance, cmd-= and cmd-+ both work. I wouldn't have expected it to work. Perhaps the shift is optional and acceptable if no other combo uses it.
