Ah. I misunderstood the requirements. Then you want
.... oops, wait a moment,
.... sigh, ...there's a bug.
well, after applying the 1 line fix below, you can simply say
pause mouse button1
leaving normal response to keys and mouse buttons 2 and 3.
That gives you zooming (button 3) and n/p/u hotkeys as usual.
The pause returns only when you click button1.
