Shortcut key for zoom with Apple 1 button mouse

Hello, I have ran into a small problem. I'm on a 2011 iMac running OS X 10.6.8 still, and normally I use the Apple Magic Mouse in the editor. I also have an Apple 1-button mouse as a backup for when I'm charging batteries. Is there any way we could have the ability to create our own shortcut keys, There is no way to zoom in and out whatsoever if you are using a 1 button mouse. I'm not asking for a complete overhaul of these keys, just the means to create our own shortcuts. 

I did a search here on the site as well as looking through the knowledge base and forums and didn't find any type of work around for this. Would this be possible?
