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.

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.
