yeah, yeah - ok.

I would still prefer something i can click with my mouse, since thats how i play the game mostly. Avoiding using keys if not absolutely necessary. Its just easier, especially in the dark.

if it was zero then i would have to take my eyes off the game every bloody time to correctly hit the zero key on the keyboard.

(though i wouldnt have anything against it being also tied to 0 for those who want it)
Just sayiinnn...
