You can disable data structure stacking by entering the :u command. When
data structure stacking is disabled, strdb does not display the stack depth.
Data structure stacking is re-enabled by entering the :s command. An
example is shown below. Note how the stack depth displayed in the upper
right hand corner of the screen changes.
