Disable “Ctrl”+mouse wheel zooming in Chrome?

Problem

I'm a normal-sighted person and I would like to view pages at 100% all the time. I use keyboard shortcuts that involve Ctrl a lot, so about twenty times a day I accidentally hit Ctrl at the same time that I'm scrolling, which results in the page being reflowed and repainted. This is annoying because it can take up to 30 seconds to fix the issue, depending on how complex the site layout is. On sites with dynamic layout such as Google Docs the problem is more serious; accidentally hitting Ctrl+mouse wheel corrupts the display and forces me to refresh the page entirely, sometimes causing me to loose information in the process. I would like to either decouple Ctrl+mouse wheel from zoom, or disable zoom functionality altogether. This is possible on Firefox by using about:config; is there a similar way to edit detailed settings in Chrome? Would I have access to the detailed settings if I used Chromium instead of Chrome? I'll probably jump ship back to Firefox if I can't solve this problem. …
