Keymap to copy value from "Show unique XPath" into clipboard

Hello everyone,

Each time I use "Show unique XPath" feature, I have to move the cursor to the right of appeared popup to copy the value into clipboard. How can I do it quickly using keyboard? Tried CTRL+C, but it copies current line content, not the evaluated XPath value. Seems like I am missing some obvious thing here... :)

I am using IntelliJ IDEA v13 (IU-133.696), it if matters.

Thank you,
Dmitry
