I don't think you can overwrite application shortcuts with website code. Imagine a site overwriting alt + tab, and suddenly you wouldn't be able to tab out of your browser window anymore. It is possible with some plugins, but that depends on the browser you're using.

Instead, use something that isn't a default keyboard shortcut to prevent other users from having the same problems. Everyone expects and counts on ctrl and +- to change their zoom level; overwriting this simply isn't a good idea usability-wise.
