Screen Appearance

Dear Experts,

I am using version  SAP Business One 9. PL : 04.

Hereby I attached my screen shot.

In that Item Master, when I drag down they only Add  & Cancel buttons are showing.

Is there any option to fit add & cancel button means by default it has to show in the screen.

Also, Is there any shortcut for switch between screens in SAP Business One Application.

Please help on this.

Thanks & Regards,

Silambu
