How to select a bunch of connected surface region in a quick way

This is a work around that I am using and find it quite useful:

1. I select the edges around the region of a surface that I want to select.
2. Then I create a temporary seam by:
   ==Right click > Mark Seam
3. Then go to face selection mode.
4. Select a face that is inside the region that you want to select.
5. While keeping your mouse cursor inside the region that you want to select press L on your keyboard.
   L = Select Linked

This method should select all the faces that remains inside the seam that you have created temporarily.
