Qt creator editor file completion keyboard shortcut

[avi.levi]

Hi,
I'm working with Qt creator 5.7 on openSUSE and would like to be able to complete file/directory paths in the editor using a keyboard shortcut.
Similar to vim ctrl-x ctrl-f.
Is there such a shortcut?
Using vi-mode (Alt-v Alt-v) and trying ctrl-x ctrl-f does not work either.

Thanks
Avi
