Description Chris W. CLA 2018-05-16 04:03:00 EDT 
Currently, there is the word completion functionality (mapped to alt+/ by default) that cycles through candidates in order.

Desirable would be to have this cycling available also in reverse order.

This is useful in situations where one cycled too far and wants to select to previous candidate.

Currently, one has to cycle through the complete list once more.

If desirable, I could, with some pointers to the right extension points and helping material, implement such a feature myself and contribute it to the eclipse code base.

See org.eclipse.ui.texteditor.HippieCompleteAction.

You probably want to add #completePrevious to that since you need the current state to go back.
