Cell selection, navigation between input areas, and confirmation of entered values are performed using the arrow keys, mouse, and Enter key. This approach aligns with common practices in spreadsheet applications such as MS Excel. Planners can use the arrow keys to select individual cells, and the Escape key can be used to cancel an input in the active cell.
Another option is to use the mouse, which provides the same functionalities.
Note: Only editable cells respond to the keyboard. This ensures that the data is protected from unwanted changes.
