"Apply modifiers" button not appearing? I am attempting to follow a youtube tutorial for decimating a model - I need to do this for a continuous LOD in a game I am creating.

However, in the tutorial, he uses some "Apply modifiers" button, which I can't find anywhere!

If I start up blender with the default box, I see it, but when I open a .blend, or import a model, the button disappears!

What am I doing wrong here?
The apply modifier button will be on the modifier.
Blender 2.9x
In Blender 2.9x click on the top triangle to apply the modifier, or use Ctrl+A.

See: How to apply a modifier in V2.9+
Blender 2.7x

You have to be in object mode to apply modifiers. Applying the  modifier does not work on multiple selections, only the active object gets applied.
