Creating boolean animation clip curves

Creating float curves is done with:

Code (CSharp):

1. var keyframe = new Keyframe[10];
2. keyframes.value =1f;

Creating object curves is done with:

Code (CSharp):

1. var objectkeyframe = new ObjectReferenceKeyframe();
2. objectkeyframe.value = someObject;

But I can't find how to create a curve that has booleans in it. I tried to do it with the keyframe way and set the value to 1 or 0, it works but it displays weirdly in the animation window i.e. not with the trigger on and off but with number being 0 and 1.
