In the Schema browser, when looking at the data of a referencing table, the Foreign Key lookup can be displayed by doing a single-click in the cell.
However, when adding a new row to the same table, the Foreign Key lookup can only be displayed when inputting anything in the cell first.
How can the new row be edited without having to press anything in the keyboard first?
1. Go to menu View | Toad Options | Data Grids | Visual.
2. Check option "Immediate edit".
3. Click Apply and OK.
