This explains the functional steps within the sequence. For all the other XML details please refer to Formats and syntax

• The first and last two lines Handles.ClearSelection() and ActionScript.SetProperty(“Playbacks.Editor.SelectedPlayback”, null) make handle and playback selection empty so that no other handle/playback is affected by accident.
• Handles.SetSourceHandle(“PlaybackWindow”, 0) selects a playback as source handle
• <step condition=“Playbacks.IsCueHandle(Handles.SourceHandle)”>: only if this is a cue playback handle (and not maybe a macro or group handle which would break the macro)…
• … ActionScript.SetProperty(“Playbacks.Editor.SelectedPlayback”, Handles.SourceHandle) derive the playback from the given handle (the playback holds the time, not the handle)
• Playbacks.Editor.EnsurePlaybackCueSelected() is required for single-cue playbacks to make sure the cue itself is selected/in the editor
• ActionScript.SetProperty.Double(“Playbacks.Editor.Times.CueSpeedMultiplier”, Math.Cast.ToDouble(0.25)) finally sets the multiplier to the desired value which needs to be a double, hence the value is cast with Math.Cast.ToDouble(0.25).

• make this macro available
• while it's well possible to create some macros to set some playbacks to a given multiplier, it does make more sense to integrate this into a bigger context like Create Workspaces in order to setup a known show environment.
