hibernate methods in Fedora 20?

edit

On my F20/KDE, I did configure a keyboard shortcut in KDE daemon's shortcuts (I assigned Ctrl-Alt-H ). Before finding this I either used ~ sudo pm-hibernate (requires some stuff in /etc/sudoers) or barely the KDE desktop's GUI action (but I dislike this since it requires more gestures than just the keyboard shortcut)

I always use systemctl hibernate in terminal, which I keep open all the time. Works fine for me, but a simple GUI solution would be handy for me too.
