How to add "keyword search" in TT-RSS (e.g. in Firefox)?

[aratistern]

Firefox and other browsers allow to define keywords to use a specific search engine when looking up information so that e.g.

g searchterm

in the address bar opens up a window with

https://www.google.com/search?hl=en&q=searchterm&gws_rd=ssl

Is it possible to add a such a keyword search for the TT-RSS search field?
And have certain parameters added to it (e.g. "all feeds", "current feed" etc.)?

It's possible to make a plugin which will parse additional command line parameters to index.php or something and pop up the search dialog automatically but there's no such functionality in tt-rss at the moment.
