Writes the edited value to the register and closes the dialog box.


The edited value is not written to the register until you click Set. This means, closing the dialog box with Close will discard all changes.

Restores the original register value in the dialog box.


You can only restore the value until you click Set. When you click Set, the edited value is written to the register. Reopening the dialog box will display the edited value as original value, this means Restore cannot reset the register to the original value that was displayed in the previous dialog box.
