Red Flags on Frames in Timeline

[dzylum]

There usually have notes in them but I can't figure out how to access them.

Sorry?

You're talking about the "Frame labels" right?
They can only be placed on keyframes, and if you can't see the label on the timeline, it's most likely because there's another keyframe right next to it.

As for accessing them, are you talking about accessing them with actionscript?
just use:

gotoAndStop("framename");

of

gotoAndPlay("framename");
