Windows 365 streams a full Windows Cloud PC to your Mac for $28–$66 per user per month (Microsoft US pricing, August 2026). Every Excel Alt shortcut works, but you need internet, you feel the latency, and IT usually owns it. Accelerator Keys adds the same Alt sequences to native Excel for Mac for $39.99/year, offline. Windows 365 if IT provides it or you need Windows apps; otherwise Accelerator Keys.
| Accelerator Keys | Windows 365 / a cloud PC | |
|---|---|---|
| Cost per year | $39.99 (Excel) or $59.99 (Excel + PowerPoint) | $336–$792 per user per year ($28–$66/month, Business or Enterprise, 2–4 vCPU) plus a Microsoft 365 subscription for Office |
| Setup time | About 2 minutes: install, grant Accessibility permission, done | Minutes for the end user if IT has provisioned it; hours to days for IT (tenant, licenses, Intune, images, sign-in policies) |
| Keystroke latency | Native — the app sends the ribbon command directly to Mac Excel | Every keystroke and screen update travels over the internet to a data center and back. Fine on a good link, laggy on hotel Wi-Fi |
| Battery and CPU | Negligible — a 20 MB menu bar app | Light on the Mac itself (it only decodes a video stream), but you are streaming video for the whole session |
| Needs a Windows license? | No | Included in the Windows 365 subscription; Enterprise plans have extra licensing prerequisites |
| Works offline? | Yes | No — the PC lives in Microsoft’s cloud. No internet, no Excel |
| Alt shortcut coverage | 900+ Excel and 380+ PowerPoint ribbon sequences, plus legacy Alt+E / Alt+I / Alt+O / Alt+D, with KeyTip badges on the ribbon | 100% — it is Windows Excel. Note that on a Mac keyboard, Option acts as Alt inside the remote session |
| Windows-only Excel features (Power Pivot, Power Query editor, some VBA, some add-ins) | No — you are still in Excel for Mac | Yes |
| Files stay in native Mac apps | Yes — Finder, Spotlight, iCloud, Mac fonts and printing all work as normal | Files live on the Cloud PC or in OneDrive; local Mac files need redirection or a sync step |
Out of the box, Excel for Mac does not respond to the Alt key. Press Option and nothing happens on the ribbon, because macOS uses that key to type special characters. If you learned Excel on Windows, hundreds of shortcuts stop working the day you switch.
Windows 365 and Accelerator Keys fix this from opposite ends. Windows 365 gives you a Windows PC. Accelerator Keys gives Mac Excel the missing key.
Windows 365 is Microsoft’s Cloud PC service. Microsoft runs a Windows virtual machine in its data centers, and you connect to it from your Mac through the Windows App or a browser. Inside the session, Excel is Excel for Windows. KeyTips appear when you press Option (which the session sends as Alt), and every sequence works.
What it costs, as of August 2026, from Microsoft’s US pricing pages:
Over a year that is $336 to $792 per person before Office. For a company that already runs Windows 365, the marginal cost of Alt shortcuts is zero. For an individual, it is a lot to pay for a keyboard feature.
Accelerator Keys is a native macOS menu bar app. When Excel or PowerPoint is in front, it watches for the Option key, shows KeyTip badges on the real Mac ribbon, and runs the command you type.
A Cloud PC on a strong connection near its data center feels close to local. On hotel Wi-Fi, a train, or a home link shared with a video call, you feel every keystroke make the trip. Fast modellers notice this most, because Alt sequences are typed in bursts and a lagging screen breaks the rhythm.
Accelerator Keys has no network path. The command goes from the app to Excel on the same machine.
Yes. Some people use a company Cloud PC for the Windows-only tasks and native Excel with Accelerator Keys for everything else, especially when travelling. Inside the Cloud PC, Windows Excel already has Alt shortcuts, so Accelerator Keys is not needed there.
It is macOS only and covers Excel and PowerPoint only. Word support is planned for Q3 2026 and is not shipped. It is a subscription. It needs Accessibility permission. It does not give you Windows, and it does not add Windows-only Excel features.
Windows 365 is a good way for IT to hand out managed Windows desktops, and if you already have one, your Alt shortcuts are already there. As a way for an individual Mac user to get Excel shortcuts back, it is a $336-to-$792-a-year, internet-only, slightly laggy answer to a $40 problem. If you need Windows, use Windows 365. If you need Alt, H, O, I, use Accelerator Keys.
As of August 2026, Microsoft’s US pages list Windows 365 Business at $28 (2 vCPU/4 GB), $36 (2 vCPU/8 GB) and $56 (4 vCPU/16 GB) per user per month, and Windows 365 Enterprise at $31, $41 and $66 for the same tiers. That is $336–$792 a year per person, before your Microsoft 365 subscription. Check Microsoft’s pricing pages for your region.
Yes. The Cloud PC runs real Windows and real Excel for Windows, so KeyTips and every Alt sequence work as on a PC. On a Mac keyboard the Option key is sent as Alt inside the session. The trade-offs are the monthly cost, the need for a live internet connection, and the small delay on every keystroke.
It depends on your connection. On a fast wired or Wi-Fi link in the same region as the data center, typing feels close to local. On a slow or shared connection, or when travelling, you notice the round trip on every keystroke and scroll. Accelerator Keys runs locally, so there is no round trip at all.
When your company already provides it, when you need Windows-only applications beyond Excel, or when IT wants a managed, wipeable Windows environment on personal Macs. In those cases the Alt shortcuts come along for free, and Accelerator Keys is not needed inside the Cloud PC.
You can have both on the same Mac. Inside the Cloud PC, Windows Excel already has Alt shortcuts, so Accelerator Keys is not needed there. In native Excel for Mac, which is where you work offline or when the connection is poor, Accelerator Keys restores the same shortcuts locally.
