Editing or deleting one of several rectangle selections

[jbheadrick]

Hi,

Just started using GIMP, just found this forum, have a question I haven't been able to answer through my own research.

Let's say I use the Rectangle Select tool (in "Add to the current selection" mode) to select 10 different regions of my image.  Then let's say I want to change the size or delete rectangle selection #7.  How do I do this?

I know that I can use Select > None or do a Shift+Ctl+A to delete ALL of the rectangle selections, how do I edit or delete just ONE rectangle selection?

So, two questions:
   

1. How can I delete one of several selections without having to start over?
       
   
2. How can I edit a particular selection, such as changing its size?
   

   
Thanks for anyone's help.
