Windows The Windows version of Excel has the longest-established shortcut set and is what most Excel tutorials, certifications, and documentation use as their reference. F-key shortcuts work without Fn by default and are particularly important in Excel on Windows. The Alt key activates Ribbon key navigation, giving keyboard access to every Ribbon command.
Mac The Mac version uses Command (⌘) as its primary modifier. F-key shortcuts — which cover several important Excel operations — require the Fn key by default on Mac unless you've changed the F-key behavior in System Settings. This is the most notable practical difference from Windows for heavy Excel users.
Web Excel for the web runs in a browser on any operating system. The modifier key follows the host OS — Command on Mac, Ctrl on Windows. Most core shortcuts work; a few desktop-only features and their shortcuts are not available.
iPhone Requires an external keyboard connected via Bluetooth or Lightning. Covers cell navigation, formula entry, and basic formatting. The shortcut set is smaller than on desktop.
Android Requires a Bluetooth keyboard. Coverage is similar to iPhone — focused on the cell and formula operations that make mobile spreadsheet work faster.
