When using a small display, the list of operators is truncated

When using a small display, such as the Raspberry Pi touch screen, the list of operators is truncated.

Steps to reproduce:

1. Open orca-c
2. Open the Main Menu, then select the option to display the list of operators
3. The list of operator appears

Current result:
The list displays operator A to M, but not N and after.

Expected result:
The list of operator continues on the other side like the Windows version:

Alternative: Maybe allow to navigate/scroll the list using arrow keys?

I am also trying to find a solution to this. Two columns list would be preferred on small screens.
