Hey all. I just randomly tested a bang for jisho and it works! If you use DDG as your default, you can search in jisho simply by typing !ji (what you want to search) or !jisho (what you want to search). This can help you look things up super fast on the fly.
"Oh, what did the verb kuu mean again? Oh let me check. ctrl+t, !ji kuu - done. Also works for searching with kanji.
