Is there a way to zoom in on PDF preview window?

Is there a Configuration setting or a Shortcut Key to zoom in on the Preview window.

Try numpad + and -.

Edit: Just tested it myself, doesn't work for pdf's with PDF X-Change.

Numpad + and - work in the Floating Preview (F11) if the preview is just a plain image (e.g. a thumbnail of a PDF). However, if the preview is controlled by a preview handler, then the available keys will also be controlled by that handler.

Using PDF-XChange as previewer shows its Zoom buttons inside the preview.
