Information Window of picked objects can be shown/hidden by Windows > Information > Information Windows. It not only allows us to view the information, but also to edit some of the various parameters displayed in it. Some examples.

• Change the parameters of key point geometry (radius, length, etc.)
• Change name and transform values of objects
• Change geometric constrain tolerances in surface continuity locators.
• Change values of CurveCurvature locators.
• Change annotations

... and a whole lot of other info/values. Try toggling Information Window (CTRL + 5) on active objects and locators and see the possibilities. It can be also used to change values of IK handles, constrains ..etc.
