Can you be a bit more specific?
If you want to past text from a clip board while you’re authoring: select and copy it in the usual way (Ctrl+C) then paste into a text field (Ctrl+V).
If you want to import the text at runtime then you need to use the loadVariables() or loadVariablesNum() method to load a txt.file
If you want to import text at runtime and then apply conditional formatting you could conside using the xml.load() method to load an xml document.
