Could not nudge the selection because the pixels in a type layer cannot be modified without first rasterizing the layer.

This has been bothering me for years. I finally took a couple of seconds to Google it, and it seems Painted Digitial has a fix:

What I realized was that this was the result of using the marquee tool earlier and somehow improperly deselecting. If you happen to run into this problem, all you need to do is grab your marquee tool and select an area then deselect. Or, you can go up to the Select menu, and click deselect.

Or ⌘D.

I like Max's solution to the problem:

I have this problem all the time… haven’t found a way to prevent it, but I defined a keyboard shortcut for Layer > Layer Style > Clear Layer Style.

I picked ⌘X.

I’ve never found it useful to inherit the style. I can see why they thought it would be, but I find it unpredictable. Jonathan pointed out that a style “sticks” when the shape tool is selected at the same time an existing shape is highlighted. It’s true, but then that style doesn’t unstick until you tell it to, whether there’s a shape highlighted or not.

I’d rather have it as an option disabled by default, or really, just throw the whole thing out.
