Save Selection
Here you can save a selection permanently. So it will stay with you. You can save either a polygon, edge or point selection. You can restore these at any time by double-clicking on the small icons in the Object Manager:
Saved point selection
Saved edge selection
Saved polygon selection
If a selection tag already exists and is selected and the command is called by holding down the Shift key, it is overwritten.
You can find out how to assign separate material properties to saved polygon selections under Selection. Saved selections are also very important for deformation objects. You can find out more about this under Deformation.
