A question on a basic photoshop function

[Diginova]

When I paste a small block of texture onto a new layer, how do I stretch it across the entire layer?

I suddenly blanked out, sorry. sweatdrop

Normally you should just be able to pull at the corner when you first paste it to make it larger or smaller or you can use the tool that looks like an arrow at the top left ( Sorry I dont remember its name) And that should let you size it however you want and if that also fails then you should be able to just go to the top where the tabs are at and click image, then Image size and make it bigger.
