It's F5, F6, F8, F9, F10, F11 definitely. I never use the F-keys for anything except changing terminals, and I use only four text terminals, one graphical, and an error console. (Update: just realized that VNC uses F8.) Pause is also mostly useless but a few games recognize it.

The SysRq magic is useful. Scroll Lock is sometimes useful to stop text (also it's the way to view the scrollback of the terminal on FreeBSD by default).

I definitely use Caps Lock. Its original purpose is not only useless but even harmful, as I press it accidentally too often. Thus, I've remapped it to write accented letters: it's easy because it's not too far to reach and I can hold it with my left hand while I type the accented letters with my right. It now works like this both on console and X.

I use Backspace, Escape, and # too.

Finally, I don't have a Windows key. I use a 101-button keyboard with no extra buttons on principle.

What's left? Ah, Mac key. I don't have one. Last time I had it was when I used a Commodore 64, although they called it the Commodore key there.

    [Eily]: since the value of a node is also the sum from the two nodes above, you just have to demonstrate that the equality is true at the top of the triangle
    [Discipulus]: yes Eily, thanks oiskuu but i dont get it.. ;=( maybe I'll ask a SOPW
    [LanX]: all combinations with same amount of left and right?
    [Eily]: if you want to store in a structure with the coordinates as key, arrays might do, since the keys are going to be 0..n
    [LanX]: (Pascale path)
    [Eily]: paths like that
    [Discipulus]: yes Eily++ (very keen) I want to integrate my project with a 17th experiments. I want to colorize in sequence all paths
    [oiskuu]: Yeah, modifry the recursive func combinations() to return not the number, but the paths themselves.
    [Eily]: Discipulus I'd do that by starting from the bottom node I think. That way it can inherit the paths from the two nodes above (and so on, recursively)
    [LanX]: oh I meant fixed amount
