How to copy/paste in browser GP

• ctrl-C and ctrl-V always copy and paste text within GP

• the paste command from the menu always pastes text from the system clipboard into GP

• dropping a text clipping onto the GP browser window is an alternate way to paste text

• in Chrome and Firefox, ctrl-C copies the selection from GP into the system clipboard, but in Safari you must manually invoke the "copy" command from the browser menu to finish transferring the selection to the system clipboard.
