>For instance if you want to do a find/replace in VS you can double click on a word do Ctrl+H and the word you selected populates the search box

I'm fairly sure Xcode has a command "enter search/replace string" that puts the current selection into the search/replace box.

Across all (Cocoa?) Mac apps, cmd-e should do it. It definitely works in Xcode.
