It is difficult to deselect specific unwanted cells whenever we use the Ctrl+select shortcut key. It is extremely vital for managing huge data over thousands, one mistake will cost me to re-select all of them again.

This is completed now, isn't it?
Can't believe they "accidentally turned on" this feature for Office 2016 and decided to turn it off. Why wasn't this a basic feature in the first place? https://techcommunity.microsoft.com/t5/Excel/Unable-to-deselect-in-excel/m-p/363008/highlight/true#M26886

When is this basic functionality going to be restored for Office 2016 users?
Currently , the deselect feature is not working on the latest version of Excel (Office 365)
This feature has been added and is rolling out to all Office 365 customers.
