I'm in the Editor
I type 'select * from dbo.' to bring up the picklist and then start to type the first few letters of a table.
Once the table is found, I click to select that table.
However, in the editor it removed the 'dbo.' from the query i.e.
select * from table_name
select * from dbo.table_name
Scroll to the desired object instead of typing part of the object name
Waiting for fix in a future release of Toad for SQL Server
