How can I copy or paste text into the Script Editor?

This will copy\paste data in the top half (the 'reporter') of the Script Editor:

cmdScrollFieldReporter -e -copySelection "cmdScrollFieldReporter1";
cmdScrollFieldReporter -e -pasteSelection "cmdScrollFieldReporter1";

This will copy\paste data in the bottom half (the 'executer') of the Script Editor:

cmdScrollFieldExecuter -e -copySelection "cmdScrollFieldExecuter1";
cmdScrollFieldExecuter -e -pasteSelection "cmdScrollFieldExecuter1"
