What steps will reproduce the problem? 1. Hold Control Button 2. Use Mouse wheel to Scroll Up 3. Use Mouse wheel to Scroll Down

What is the expected output? What do you see instead? I expect that this will perform the zoom-in and zoom-out functions. This is a common control in many applications (Word, Firefox, GIMP). It makes navigating a document easier.

What version of the product are you using? On what operating system? 1.0.4 on XP

Please provide any additional information below.

Fully agree with this... still trying this :)

I use version 1.2 and I'm really happy about zoom feature, thanks! however, in current version zoom center is the upper left corner of the canvas (I suppose).. use instead the mouse pointer location as the zoom center, so the user can decide where to zoom.

Shortcut is good, but I think we need a zoom button!
