Auto-trigger 'Hit Enter Key' or 'Click Check'

Hi Guys,

How to automatically trigger 'Enter' without hitting enter?

Here's my scenario:

I have multiple tabs each have editable ALV in it.

While navigating in between tabs, the changes that I made in the ALV doesn't get saved in the display IF I just input and move to the next tab.

It will just be saved if after inputting, I click any buttons in ALV (like check, insert, delete rows, etc ) or hit 'Enter' before moving to the next tab.

I am thinking, is it possible to code 'Hit Enter Key' or 'Click Check', so that the user need not perform those actions and at the same time the changes reflected will be saved?

If yes, how?

I was looking at this link:Automatically Trigger onEnter event after selecting value from the Value Help(F4 Help), but the methods are not yet available in our system.
