Keyboard use in browser extension

My request has to do with the browser extension. With 1Password I could start typing in the extension search bar to find the site I want to go to, then arrow down on the keyboard and hit Enter to go there. Super fast. But with BW the process feels super awkward. I use my mouse to click the BW extension and then the search field, then switch to the keyboard to type my search, then switch BACK to the mouse to click the tiny launch icon.
