Pasting filenames into editor

edit

Is there a good way to paste file and path names? I have always been copying from Windows explorer via "Copy as path", pasting into Wing and adding an 'r'.

E.g.

r"C:\Program Files\Wing Pro 11\bin\wing.exe"

This is awkward and has e.g. problems when you have a path like "...\U...". Is there a keyboard shortcut or e.g. a modifier key to drag a file to an editor window to insert the path with double backslashes? Alternatively, is there a Wing script?
