It would be good to have some support for Kiwix. Kiwix is an offline reader for web content, most notably Wikipedia.
Here's what I suggest:
By typing in the keyboard wiki, and then following it with some text, it will preview the associated Wikipedia artice.
Pressing enter will open the article in Kiwix.
