How to control Enter key (or data changed) using REUSE_ALV_GRID_DISPLAY?

Hi all,

I have an editable ALV, using FM "REUSE_ALV_GRID_DISPLAY". I like to check when user changes the data from a cell or when press Enter key. How can I do it?

REMEMBER: It's isn't a OO ALV, I'm showing it througth FM.

Regards,
