Combining information from a couple of other answers: If you want to yank the current full path to a file and put it into the command buffer in another window, first do :let @" = expand("%:p"), then move to another window and type Ctrl+R ".

Useful for copying a file while staying in the same directory and keeping the old one open. For example:

Start: Editing src/com/benatkin/paint/shapes/Circle.java

1. Type :let @" = expand("%:p") (The path gets yanked to the main clipboard buffer.)

2. Open a new window with :sp

3. Type :e Ctrl+R"

4. Use the arrow keys to go back to Circle and change it to Square, and press

End: Editing src/com/benatkin/paint/shapes/Square.java
