In the Trial version of Toad 11 I am able to do a "select * from" and a space and a list of table will show up. Now in the Toad commercial version it's not doing that. customer wants to know what option to turn on for that.
Go to the menu View | Toad Option | Editor | Code Assists, in the top left hand corner, check the box for "Expected Tokens". Then click on Apply and OK.
