<!--[if gte mso 9]><xml> <o:OfficeDocumentSettings> <o:AllowPNG/> </o:OfficeDocumentSettings> </xml><![endif]--> Hi all,

My Excel 2010 short cut keys - Ctrl + Left or Right Arrow Key - are not working anymore. However, the short cut keys - Ctrl + up or down arrow keys are working. I will appreciate it if the learned community member can guide me to recover these handy short cut keys. Thanks in advance.


I am using ASUS N53S laptop.
