prefill the search panael text box with the selected text from the current editor

usecase: if DCD does not work or is not responsible i like to be able to select some text and then search for other occurrences.
If the ide automaticlly prefill the textbox for the search it much more comfortable.
It is standard behaivor in many (maybe every) popular applications (firefox, openoffice ...)
