Windows Ctrl is the modifier throughout, plus a few function-key shortcuts (F9/F10 for the Recorder, F1 for help) and a PowerPoint add-in with its own recording shortcuts.
Mac Cmd replaces Ctrl for most editor commands, though several Recorder, timeline, and library shortcuts use Control or Option instead, and a few Windows-only shortcuts (the PowerPoint add-in, several library navigation keys) have no Mac equivalent at all.
