Inconsistencies / confusion with documentation Index Tab. Example (line numbers added for comments that follow):

1 max
2   built-in function
3 max  (datetime.date attribute)
4   (datetime.datetime attribute)
5   (datetime.time attribute)
6 max() built-in function
7   (decimal.Context method)
8   (decimal.Decimal method)
9   (in module audioloop)

The following all lead to confusion and frustration:
Having 3 rows (1, 3, 6)that begin with max. 
Having an entry (1) that does nothing when double-clicked.
double-clicking (2) takes us to a reference rather than a definition.

RECOMMENDATION:
change to:
max() built-in function
  (sequence operation)
  (decimal.Context method)
  (decimal.Decimal method)
max
  (datetime.date attribute)
  (datetime.datetime attribute)
  (datetime.time attribute)

where double-clicking the first line goes to the max() definition
in 2. Built-in Functions


These comments apply, with a number of variations, to most built-in functions index entries.
