The low tech way is that when viewing a record, as usual, the good stuff is hidden under the little "More ..." button at the top right. One option is to copy the record. You are in control of which fields copy forward, as this is a field property setting on every field type. The default is to Copy.
If you want to make a button, you can make a formula URL button with this code
URLRoot() & "db/" & Dbid() & "?a=GenCopyRecord&rid=" & [Record ID#]
You can set it to appear as a button and chose a color. I suggest only showing the button in View mode on the form.
