keyframing multiple lines of text at the same time

Is it possible to keyframe multiple lines of text at the same time?
I have 3 lines of text that i want to animate (change to 0% opacity)
When i select the 3 lines an add the keyframes and change the opacity only one of the lines change.
Not sure what to do. create compound clip?
thanks
owen

i figured it out but the fix doesn't make sense.

i used the film icon button instead of "T" and selected all clips and adjusted opacity that way with keyframes. Could someone explain that to me? thanks

The Title inspector is for the published parameters from Motion. Basic Title for instance has no published parameters. You can animate the opacity in the Text inspector, that's the one next to the T, but you might have to animate, Face, but you might have to also animate Outline, Glow, and Drop Shadow. The Video inspector is the overall video opacity of the item.
