Track View > Track Selection toolbar
You can assign a name to the current track selection, and then later reselect those tracks by choosing the name of the respective track set from the list.
You can also create and edit track sets with the Track Sets Editor dialog.
If you are animating track sets using Key Filters in Set Key mode, the filters dictate which track set members are keyable, because they take precedence over track sets.
To assign a name to a track set:
Highlight one or more tracks in the Track View Controller window.
Click in the Track Set List field on the Track View toolbar.
Enter a name for your track set. The name can contain any standard ASCII characters, including letters, numerals, symbols, punctuation, and spaces.
Press Enter to complete the track set.
You can now highlight another combination of tracks and repeat the process to create another track set.
To edit a track selection:
You can change a track selection using track sets and the Ctrl and Alt keys.
Highlight one or more tracks in the Track View Controller window.
Press and hold Ctrl, and then click a name in the list.
The track set members are added to the current track selection.
Press and hold Alt, and then click a name (either the same or another) in the list.
The track set members are subtracted from the current track selection.
To edit track sets;
On the Track View toolbar, click Edit Track Set to display the Track Sets Editor dialog.
