Menu commands for selecting

Peter 27Feb13: ToDo-2 This table really needs extending with an additional column for the relevant keyboard shortcuts - but watch the width!
And would we want a D4 alternating colours type table as we recently settled on for the Edit Menu page?

• Gale 02Mar13: In principle no, as it would be identical in aim to the tables on Keyboard Shortcut Reference so arguably would follow their style. OTOH there is another table below it which is just shortcut and action which arguably could be D4. ATM I think not D4 for either, they are not basically custom TOC's-with-links are they, which is the Edit Menu purpose?

The Edit Menu has several commands that are useful for selecting.

Edit > Select command	Action
All	Select all tracks, including the entire content of audio tracks and note tracks.
None	Deselect all tracks, removing any selection they contain and setting the cursor at the start of the former selection region.
Left at Playback Position	Sets the left selection boundary at the current playback position, otherwise opens a dialog for moving the left selection boundary.
Right at Playback Position	Sets the right selection boundary at the current playback position, otherwise opens a dialog for moving the right selection boundary.
Start to Cursor	Select from the start of the track to the cursor position.
Cursor to End	Selection from the cursor position to the end of the track.
Region Save	Captures the currently selected time range or cursor position.
Region Restore	Restores the time range or cursor position from Region Save.
In All Tracks	Extend the current selection or cursor position up or down into all other tracks.
In All Sync-Locked Tracks	Extend the current selection or cursor position up or down into all other tracks which currently have the Sync-Lock icon   .

Select > All	CTRL + A	Selects all of the audio in all of the tracks.
Select > None	CTRL + SHIFT + A	Deselects all of the audio in all of the tracks.

Select > Right at Playback Position	]	When Audacity is playing or recording, 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).

Menu items assignable in Keyboard Preferences: Region Save; Region Restore; Play Region Lock; Play Region Unlock. Holding SHIFT then left-clicking in the waveform creates a selection between the editing cursor and the click point (or extends the existing selection from its nearest edge). This shortcut cannot be configured in Keyboard Preferences.
