What is shortcut for setting primary key in SQL Server 2008?

I am creating a table, how can I set primary key for my table without using my mouse ? I wanna do this with my keyboard (short key).

What is CTRL L in SQL Server?

To find this out, press CTRL+L to display the estimated query execution plan as shown below without actually running the whole query (in fact it runs for top 1 row).

Try with: Alt+L,Y (case insensitive).

That keyboard shortcut will mark as PrimaryKey of selected column (on design mode).

Here is an example:

CREATE TABLE Persons
(
P_Id int NOT NULL,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Address varchar(255),
City varchar(255),
PRIMARY KEY (P_Id)
)

P_Id is the column with the primary key constraint.
