Managing datagrid with keyboard

[Aliquo]

Hi there!

I'm developing a WPF view with a grid and I would like to use the keyboard instead of mouse to control it. These are the features I have to accomplish:

- Using a combination of keys, enable or disable datagrid editing. Done

- When enablind datagrid, set the position in a new row with default values. Pending.

- Using keys to modify data, using tab/enter/arrow keys to move through cells. Done.

- When new row is completed, move to a new row with default values. Pending

Hope you can help me to accomplish pending features.

Thanks in advance

Victor

PD: I'm using MVVM approach
