How to make a selection around another selection
This is relatively rare but you may want to select around something that’s already been selected. This will create a duplicate selection. And here is how you do it:
Make your selection with any given selection Tool
When you choose the command „Select” go on to “Modify” then click on „ Border”
Choose a given number of Pixels between 1 and 200. This will give the new border width of the selection from the earlier selection. This means 1 is super close and 100 and above is very far
Click „Ok” to finalize your selection.
This action will literally duplicate the earlier selection only it will make it larger than the previous one.
