Steps to reproduce:

Set the keyword for Google Search in One-Click Search Engines to "google".
Type "google stock" in omni bar, click enter.

Actual results:

"stock" is searched in Google Search.

Expected results:

"google stock" is searched in my default search engine.
What I want to say is, using spaces as triggers of One-Click Search Engines can be confusing, it could not tell whether it's the trigger or just the keyword you want to search for. Why don't we change it to the tab key just like Chrome does, so we can have both a consistent experience between browsers and a clearer user experience.

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

If you start the keyword with the @ character (eg. @google) it solves this confusion and it also auto-completes when pressing Enter. I agree that this could be made clearer and easier to invoke.

but it is NOT good as Chrome one because it only works with built-in search enignes
