How-To Geek

I have Ubuntu and Vista on my HP laptop (single Hard drive). Vista loads by default but I would like a way to load Ubuntu without having to go to the GRUB menu (esc, up,up,up,up,enter) to load Ubuntu for when I am at home. I still need to have Vista as my default boot option. Is there a way that before GRUB loads I can just hold the L key and GRUB will load my Ubuntu option instead? It doesn't have to be the L key I was just using that as an example. I was looking through my menu.lst file but didn't see any option like that.

I was hoping not to have any menu at all (how I have it set up now) and only boot to the alternate OS when I wanted it to by holding just a key. I am guessing this isn't possible. :(

in my head it just seemed easier to make it load a option with 1 keypress instead of loading the boot menu. The boot menu isn't hard and the way I have it set up now I have minimal boot time when I am booting my default option. But I just wanted to never have to go to the menu to keep boot times to a minimal. just an example of this is like you can boot from CD by holding D in apple's open firmware and netboot by holding N. Although in my case I want to boot vista by default, ubuntu with a keypress, and something else by holding a different key. If I need to I can still go to the menu by hitting esc, but if I know what I want I shouldn't need the menu.
