This little tip will allow you to copy text from a text file for example when viewing in Quick look on the Mac. Sometime you "Quick Look" at a file, and it would be good just to grab a snippet with out having to load the document into text edit for example.
For this tip you will need to go into Terminal and type:
defaults write com.apple.finder QLEnableTextSelection -bool TRUE; killall Finder
After this has been done you can copy text from files, without opening them.
