6.x works the same or similar to 5.x, but I would like you to give some thought to having the shift arrow left and right breaking before and after a single quote. Other editors do this:
‘Error while selecting Data’||SQLERRM)
But Navigator does this:
‘Error while selecting Data’||SQLERRM
Requiring me to press the single back arrow to get the text I want.
Just a thought.
