Hai dudes

Once again nice to meet you through this post guys

plz help me to solve my problem

..is there any possibility of moving the cursor the next line (ex in my case when i reach the cell L3 right from C3 ,and when i press enter it should take the cursor to the next row c4 if i enter alphabets or word in L3,

In case if i enter number in L3 ,then the cursor should moves up to M3 ,then when i press enter in Cell M3 it should move to Cell C4

Thank you very much
