Use Shortcuts to avoid fat finger issues and speed up data entry for numeric columns.
A Shortcut performs a mathematical operation on set of numeric columns which match a given Scope. 
There are 4 operations available: Addition, Subtraction, Multiplication and Division
In this example we created 2 Shortcuts:
On all numeric columns where 'K' multiplies the cell value by 1,000
On the Item Count column where 'A' adds 5 to the cell value
