Difficulty Editing a Sketch

[bobus17821]

I am trying to make a simple edit to a sketch and can't.  I think I am doing what I (thought I) learned from videos but that's not working.  What I want to do is change just one dimension in this sketch:

If someone can offer some help I would sure appreciate it.  (It seems to me that some of the most basic things in Fusion 360 are some of the most difficult.)  

Thanks,  Bob

The sketch dimension you are highlighting edits without issue.

I would like to offer a bit more sketching suggestions via my Screencast.  Since every component will be positioned using Joints, it should be modeled in relation to the model origin.  I do not know your desired dimensions or design so please know I just select "close" values.  By the way, in my color scheme, fully constrained lines turn White when the sketch is fully defined.

Thank you very much John.  In your screencast are you doing a double left mouse click?  Once your video showed me that it was not just possible but easy I fumbled around with it and discovered that it works for me with a double left mouse click.  In instructional videos I had seen I thought they were doing a singe mouse click, but many videos aren't explicit about left vs. right and single vs. double mouse clicks.  

And thanks too for the additional screencast about the importance of the origin.  In my rush to churn out some stuff I am anxious to have I get careless about the fundamentals (some of which I have not learned yet).  Of course I always end up paying a price.

I am using a double left click.  In the animated GIF below, there is another way to edit a sketch dimension real fast.  In the recording, I am not in the sketch.  I right click the sketch in the browser and select Show Dimensions.  I can then double left click to quickly edit and not even enter the sketching environment.  When you do not want to see the dimensions of the sketch anymore, right click on it and select Hide Dimensions (which I did not show in the clip).
