I recently converted from SQLNavigator to TOAD. One feature in SQLNav that I used a lot was the ability to drag a column name from the grid up to my query.
For example, I run select * from myTable. Then in the results (in the grid), I can drag a column up to my query without having to type in the name. Or even just copy the column name, so I can paste it into the query.
This would save a lot of time having to type in all the names.
