Choose the interruption you want to remove
A compact keyboard can leave a number-heavy task wanting a separate pad. The Retro 18 adds another possibility: doing a short calculation on the unit’s own nine-digit display before returning to the document. This is most attractive when local arithmetic and computer entry are both welcome, rather than when the sole aim is decorating a desk with another set of mechanical keys.
Local arithmetic does not fill the spreadsheet
The English manual is explicit that, in calculator mode, the connected device does not recognise the key presses. You can work out a total without those digits arriving in the active application. The same fact also sets its limit: the local calculation is not a promise that a spreadsheet cell receives the answer automatically.
For a fictional packing list, you might calculate a subtotal locally, then return to PC mode to enter the result. Someone who wants every number typed straight into a worksheet should remain in the input role instead. The useful distinction is where the numbers are going, not which of the two modes sounds more advanced.
The Windows shortcut is another control
8BitDo lists a Windows Calculator shortcut separately from the calculator-mode button. Launching the computer’s calculator and using the pad’s local calculator are therefore different actions. The manual also explains that changing connection mode, powering off or pressing the mode button exits calculator mode. Those are practical boundaries if the device will move between arithmetic and ordinary number entry during a task.
Keep the software expectation small
The product page lists Windows and Android compatibility and receiver, Bluetooth and wired connections. It describes Ultimate Software V2 support for firmware updates, not as an invitation to assume a freely programmable macro console. Choose Retro 18 when you want its two documented number-handling roles. If the real request is a custom shortcut bank, investigate a device whose official software actually describes that job.
