If you have a lot of bones on screen, it may be a good idea to color code or display the labels of the bones on your canvas. In the file we currently have open (
FlexiBindingExample.anme), the character's back arm is hidden from view due to the body. Not to mention, the body's bones intersect with this arm's bones, which can make navigating the bone structure confusing.
Click on the Select bone tool from the toolbar to the left.
