See lesson below:
Selection options
- get rid of it -- "shift+delete" -- fill using "content aware"
- to select what to use -- use patch tool (under the band-aid tool - "spot healing brush"
- to move - content aware move tool (under patch)
- to extend - change option bar options

Content Aware Fill
Copy your background layer.
Make a loose selection of the object you want to remove.
Use the "Fill Option" - short cut keys are "shift+delete".
Make sure the settings are set to "content-aware" and "normal" - say "ok"
Use the "Spot-Healing Brush" to fix any edges.

Patch Tool with Content Aware
Allows you to choose where you want your fill to come from. (Have you ever noticed when trying to use Content Aware - it picks up the "wrong" pixels"?)
Copy your back ground layer.
Select the "Patch Tool"

Make a selection of what you want removed - drag to the spot you want to use. (Look at your options bar to make changes to the setting of this brush)

Content Aware to Move an object
Copy your background layer.
Select the "Content-Aware Move Tool"
Make a selection around the object you want to move.
Drag it to where you want it.

Expand an object (think fence or awning...)
Still using the "Content Aware Move Tool" change the option in the options bar that currently says "Move" to "Extend".
Make a selection of the area you want expanded. 
Move it to where you want it to be.
You might need to now use the "Spot Healing Brush" to clean your edges...
