Make the Omnibox keyword configurable

[sferencik]

Issue Description

Please make the Omnibox keyword configurable. "find" is a useful search term, and it seems quite a few of my Google searches (which I type in the Ominibox) start with the term "find".

Steps to Reproduce

• Start typing your Google search query in the Chrome Omnibox (without the quotes): "find the serial number of X"
• Expected: I get a Google search with how to find the serial number of X
• Actual: After typing "find the" I notice that find+ has kicked in, and I have to start again, e.g. with "find" or "gfind" or "<ctrl+k>find". Of course I never remember to start my Chrome searches with space, just because the first word is "find".

Praise for find+

I love find+, thank you for it. I haven't used it much yet, but the one time I did use it, it saved me so much toil.
