In the past when you pressed the site search hotkey you could right away type the sitename you want to search and after that use the arrow keys to select the right one and press enter.. all without switching back to your mouse. Nowadays this aint working anymore. You press the hotkey, then you have to use your mouse to click the entry field, switch back to keyboard to fill in your search terms, switch back to your mouse and click the result you want to open.
This switching makes the hotkey useless, since you still have to switch between keyboard and mouse. I thought it would get fixed over time but it still aint fixed.
