Just found another request for the same issue and saw that you can set these keys in the key preferences, however I never unset them - so either the defaults were cleared by an upgrade to PL/SQL developer or the settings were newly added to preferences screen. Resetting the default keys configuration resets all key and I don't want to do that as I would have to reassign all my overrides again. Can you support the option of just resetting the highlighted key to its default, or at least display the default so that it can easily be reassigned. Note the I did look at the key configuration and saw that the assignments were all blank so I would have assumed that the default should have been used. I have now added CTRL+ for word-left and word-right and this now works. Note however that the other blank key configurations for the editor appear to work with default key, e.g. HOME goes to beginning of the line, END goes to the end of the line, CTRL+HOME goes to the top of the editor - so I'm wondering if there is an issue with the defaul key configuration not being used if the assignment is blank?
