How to use the save selection in Adobe Illustrator CC 2017 etc tutorial
The first thing about the selections is that is per document. A pity really but that is how it is set up.
1. Create a path and set the color etc
2. Create another path and set the color etc
3. Create another path and so on
4. Select some text etc
5. Select some of the paths
6. Go to the select menu and select the save selection command
That is it. OK, now you have your selection. You can repeat this, just go and select some other paths and do the same, select menu and save selection
You can then quickly access the saved selection via the select menu in Illustrator via the 'selection 1' 'selection 2' etc This is a super quick way of restoring a selection of paths / type etc in seconds instead of having to do that manually.
You should note that is doesn't matter if you alter the artwork, it is the path id that matters so if you change the type or change the color etc then it can still be selected
To save the selections in Illustrator so you can use them in the future in the document, simply go to the save command in the file menu and save the document and the selections are stored.
If you open a new document, you will notice that none of the saved selections are there (which is a pity especially if you have the same types of paths)
If you delete some paths from a selection, the save selection is still valid via the select menu but it will just select the items that remain (it does not restore the original paths)
There is an edit selection and this sadly does not allow for the addition or removal of paths from a save selection but it does just offer the option to remove the save selection from the menu list (which is, I suppose, useful if you build up a lot of pointless selections)
You can also use the save selection to save points. Use the direct selection tool to select some points in a path and then use the save selection command and when you select that item in the select list, only those points will be selected and all the other points will be still de-selected as before.
Obviously you have to be using one of the direct selection / anchor tools for this to be any use and if you are using the selection tool you will not see the selection of the anchor points etc
