Is it possible to open the tab opened from search bar (not address bar) as a sibling tab?

[zeroarst]

I know that address bar one cannot be implemented as already dicusssed before. But I would like to how about the search bar?
Currently it opens as an independent tab at the bottom.
Is it possible to add a key combination such as alt + enter to open the tab as a sibling tab?

For the address bar, you can create sibling tabs by setting:

user_pref("browser.tabs.insertAfterCurrent", true);

I would imagine this should work for the search bar, but I have not confirmed.

Additional information: TST has no option to do that due to Firefox's restriction - Firefox doesn't provide ability for addons to know an opened tab is from the search bar or not. Thus you need to use a generic way like this.
