You can review, or edit the shortcuts and key mappings in WorkBook by opening My settings from the Quick access toolbar.
As default the system is already mapped to use a set of key-bindings but if for some reason your browser is already using some of the same shortcuts as WorkBook, then you can edit and map up your own shortcuts, by clicking on the Add new from the upper right corner of the screen.
The Data Picker in WorkBook is intelligent and supports the following shortcuts.
|P||First day of current month|
|U||Last day in current month|
|N||First day in next month|
|L||Last day of last month|
|S||First day of current year|
|E||Last day of current year|
|+||Add a day|
|–||Subtract a day|
