Cloning from vertically aligned sample point

[Christoph_Jung]

When removing fences in the background of my pics and using the clone stamp, I always struggle to get a sample point *exactly* vertically aligned to the point where I draw. Is there a way to sample (by holding Alt), then restricting the movements of the mouse to vertical only until I've started cloning? Any other ideas?

A couple of techniques:

I more often than not use the option (Alt) button to get the "crosshair" cursor, which allows a precise alignment of where your target will be cloned to. Just remember to take your finger off the option (Alt) button before you click the mouse.

You could also use the x/y pixel co-ordinates in the info tab to align it pixel-perfect.

Thanks Eliot,
I have the crosshair cursor set as default in my preferences. Remembering the x coordinate works, but still requires some fuss when precisely getting at that point again. Isn't there anything a little more automated?

Cmd+R to show rulers then drag drag a new guide to position

[Christoph_Jung]

Tried that, but neither source nor target stamp snap to guides :-(
Thank you anyway,

no but at 200% zoom you can align the points with the cross hairs of the tool. Sure you should be using the stamp tool and not making a selection coping to a layer and moving over the area to be gotton rid of.

Copying a selection doesn't work, as the background is typically full of grass and branches at odd angels, and I need to reconnect at least the most obvious branches etc. I tried the patch tool, copying and much more, but in the end the good ol' stamp is the quickest way to do it.
