How do I... Make a Custom Toolbar Shortcut? Can I do it with a cat? Yes! 

Using JMP > Customize Menus and Toolbars > Customize JMP Toolbars and Menus on Windows 

Using JMP > Customize Menus and Toolbars > Customize JMP Toolbars and Menus on Windows > Create Men... 

Also I would suggest using script type new window if possible

Names Default To Here(1);

script = Get Clipboard();

ex = New Window("Script example", <<Type("Script"), script);

and if you wish to have the text in current script editor, I have to ask, why wouldn't you just paste it there? This can help with scripting the script editor if needed Scripting Guide > Display Trees > Scripting the Script Editor
