Windows key +
E opens a new window. Then which shortcut keys can be used to go file path in that opened window.
Found it, it's possible with the following two shortcuts:
Alt+D selects the current path in English versions (see comments for other languages)
On Windows 8, Ctrl+L can also be used to select the current path (all languages)
F4 will put the cursor at the end of the current path and expand the dropdown list of the address bar (all languages)
