I can't help your keyboard. But as for searching for everything, the bigger my local storage gets the harder time I have remembering where everything is. As long as I can remember what it's called, it comes up. Windows does it, Mac does it, Unity does it.
Sure, you can find a hierarchy on each if you really want it. But you know what? Most of what I need most of the time is easier to get to by hitting the hotkey and typing the first few letters.
