how to get more applications in the launchbar?

[Milton]

Hi all,
I use Ubuntu Precise Unity 2D with Orca 3.4.1.
With Alt_F1 I go to the launchbar and with arrow-down to the applications listed. With twice arrow-right a sub menu opens and I can delete an application from the launchbar.
With the super key I go the Dash and find all applications. A sighted person can drag an appkication to the launchbar. Shift_F10 is not working to get the sub menu for to find the option to let an application present in the launchbar. Is there a way to do so?
