Having a tough time with Prelude and Playhead movement.

Question

I'm having a tough time grasping how navigation in the Prelude Timeline works, and will try to keep my questions short and separate, rather than a long list.
1) I've added markers to a clip. When clicking-on/selecting a marker that I've added, it appears in the HUD, but the Playhead automatically moves to where I click. That may place it anywhere between the In and Out points for that marker, when what I might want to happen is to select/highlight a marker, then move the Playhead to the Out point, (perhaps in order to move the Out point a few frames). There must be something about the Playhead behavior that I'm missing.
2) How can one Play only the part of a clip that has markers? Example: I have multiple markers, but I want to Play only the footage between the In point of Sub Clip 1 and the Out point of Sub Clip 1.
Is there a way to do that?
The difficulty in doing this seems to be compounded by the situation described in Question 1 above, i.e. when I select/highlight a Sub Clip, the Playhead moves to where I click.
I've tried various key combinations in the Timeline and the Marker Inspector, but no joy.
Is there a way to select and Play only a Sub Clip from its' In point to its' Out point?
Using Production Studio Premium CS6 on Windows 7 Pro, and Prelude Help>Check for Updates tells me everything is current.

Answer 1

Thanks for your reply.
Clicking on either the In/Out point to drag either one, they move as shown in your example.
I don't know how to record video from my screen to show the behavior, but when I do what you do in the first 2 seconds of your video, i.e. click in the middle of the colored marker bar, the CTI moves to where I click,
I notice that you already have a marker highlighted, then you click from an area without markers to the center of the first marker, then the center of the 2nd marker, then the center of the 3rd marker, all without the CTI moving.
When I do those same steps, the CTI moves to where I click. It appears you're using only Comment Markers. (I can't read the Marker text to know for sure). However, I''ve also tried it with Sub Clip markers, and a combination of Comment and Sub Clip markers, and the CTI still moves to where I click.
I've looked in Edit/Preferences, but nothing there seems associated to the behavior I'm experiencing.
Is there some other setting I'm overlooking? Maybe something "connected" to how the HUD affect CTI movement?
Thanks.
PS: Does/would it matter that I'm using/working with AVCHD footage, i.e. MTS files?
