QLEnableTextSelection
Quick Look is a delightfully simple way to browse the contents of the files on your Mac without launching their parent apps. (Select a file, press the space bar, that’s it.) But if you’re looking at, say, a PDF or Word document, Quick Look can frustrate, because it doesn’t provide any way to select and copy text; if you find a snippet of text you’d like to copy and paste, you still need to launch the parent app.
I wonder why Apple never enabled this by default. Quick Look is a great idea, but it seems needlessly limited in what it allows users to do with the previews. Likewise, viewing applications using the Quick Look API can only access thumbnail images, not the full previews that generating applications make available to Quick Look.
