In terminal, I have an alias so that when I type note, a text document of my notes comes up. Often times when I'm browsing the web I'd like to make a quick note but I don't have terminal open, so I have to Shift-Alt-T to open terminal and then type `note'. And then I have to click off the terminal.

Is there anyway to access terminal commands without opening the terminal so I don't have to do so many key presses? Maybe through a lens or HUD? Alt-note would be really nice.. I know I could map terminal to Alt, but then I'd still have to click off it.
