end cell edit?

is there a function that can do this? my scenario is that i have hot keys enabled and when a user goes to do CTR-S, it calls my save function. the problem is that if they are still in a cell in edit mode, my save function doesn't pick up their changes.

PS - Alex - Thank you so much for the help tabbing from cell to cell issue i was having, the users are much happier now :)

does any one know the answer to this one??
