Ability to use DESCRIBE (SHIFT+F4) on a table in Script tab of Stored Procedure

In Toad for Oracle | Schema Browser | Procedure - In the source pane on the right hand side, it's possible to place the cursor on a table in the procedure and do a describe (F4). Would like the same functionality in Object Explorer | Stored Procedure | View Details | Script to be able to use SHIFT+F4 there
