<tip type="Photoshop">
Need to select every other row of pixels in a Photoshop document? 
 Tired of manually doing it?  Well, fret no more, there's an easier 
way.

Create a new Photoshop file.  Make it 1x2 pixels (or 2x1 if you 
want vertical selections).  Double click the layer in the layers 
palette and rename it anything you like (so you can use 
transparency).  Now delete one of the two pixels (so it's 
transparent), and make sure the other is filled.

Ok, now use the marquee tool to select both pixels, and define it 
as a pattern by going to Edit > Define Pattern.

Now, go to your original Photoshop file and create a new layer.  
Select the entire layer (use the marquee, it might be faster).

Now, you want to fill the entire selection, but not with a color, with 
a pattern.  So go to Edit > Fill and make sure you choose pattern 
from the select menu. Now that it's filled, deselect the layer.

Now, ctrl-click the new layer in the layers palette.  You now have 
every other row (or column) selected.  Deselect the layer (not the 
selection) by selecting the layer you want to edit.  You can move 
the selection with the arrow keys if it's off.

Go to town on layer you want to edit, and maybe save that other 
layer you create for quick selection later on.
