Scripting reference

This page lists scripting commands.
Yes these are the same commands as in the menus, same as in "Commands and Shortcuts" too, just presented differently.
Presented in a format useful to people using:
Macros or
Python Scripting or
AUD-DO.
Most of this page is automatically generated.
A few commands are intentionally omitted from the Macro Manager (such as "Close:") because they are unsuitable for use in Macros.
This table shows the items in the menus that are scriptable.
The Scripting Ids, parameters and defaults are all likely to change between versions.
Boolean values must be given as 1 (true) or 0 (false).

Scripting Id
Action
Parameters
Description
SetLeftSelection:
Left at Playback Position
none
When Audacity is playing, recording or paused, sets the left boundary of a potential selection by moving the cursor to the current position of the green playback cursor (or red recording cursor).
Otherwise, opens the "Set Left Selection Boundary" dialog for adjusting the time position of the left-hand selection boundary.

SetRightSelection:
Right at Playback Position
none
When Audacity is playing, recording or paused, sets the right boundary of the selection, thus drawing the selection from the cursor position to the current position of the green playback cursor (or red recording cursor).
Otherwise, opens the "Set Right Selection Boundary" dialog for adjusting the time position of the right-hand selection boundary. If there is no selection, moving the time digits forwards creates a selection starting at the former cursor position, and moving the time digits backwards provides a way to move the cursor backwards to an exact point.
SelTrackStartToCursor:
Track Start to Cursor
none
Selects a region in the selected track(s) from the start of the track to the cursor position.
SelCursorToTrackEnd:

Action
Parameters
Description
ToggleSpectralSelection:
Toggle Spectral Selection
none

Scripting Id	Action	Parameters	Description
SetLeftSelection:	Left at Playback Position	none	When Audacity is playing, recording or paused, sets the left boundary of a potential selection by moving the cursor to the current position of the green playback cursor (or red recording cursor). Otherwise, opens the "Set Left Selection Boundary" dialog for adjusting the time position of the left-hand selection boundary. If there is no selection, moving the time digits backwards creates a selection ending at the former cursor position, and moving the time digits forwards provides a way to move the cursor forwards to an exact point.
SetRightSelection:	Right at Playback Position	none	When Audacity is playing, recording or paused, sets the right boundary of the selection, thus drawing the selection from the cursor position to the current position of the green playback cursor (or red recording cursor). Otherwise, opens the "Set Right Selection Boundary" dialog for adjusting the time position of the right-hand selection boundary. If there is no selection, moving the time digits forwards creates a selection starting at the former cursor position, and moving the time digits backwards provides a way to move the cursor backwards to an exact point.
SelTrackStartToCursor:	Track Start to Cursor	none	Selects a region in the selected track(s) from the start of the track to the cursor position.
SelCursorToTrackEnd:	Cursor to Track End	none	Selects a region in the selected track(s) from the cursor position to the end of the track.
