I would like to copy a value of memory window then paste to excel in PC.How do I ?
You can use the Debug command Display (D) which prints the results in the Command window.
You can select the lines in the Command window and copy to Clipboard (right mouse click or Ctrl+C).
You can log all the Command Window output to a file:

You can also save sections of memory to a hex file:

You can do formatted output in Debug Functions:
