The only function reason to keep these fixed keys separate from those that follow is that the pseudoevent -- handler bindings are done above for these and below for the existing fixed key keys. And this is related to where the handler are defined. So keep the separation for now.

text.event_add('<<newline-and-indent>>',
'<Key-Return>', '<Key-KP_Enter>')
text.event_add('<<smart-indent>>', '<Key-Tab>')

# Add pseudoevents for former extension fixed keys.
# (This probably needs to be done once in the process.)
text.event_add('<<autocomplete>>', '<Key-Tab>')

Fix the config dialog breaking tab completion. This is achieved by removing
the key configuration options for ``<<smart-indent>>`` (Tab),
``<<newline-and-indent>>`` (Return, Enter) and ``<<smart-backspace>>``
(Backspace) from the configuration mechanism, making them hard-coded
instead.
