As stated in post above, you need to have a heal type charm in main or acc slot and press either E (Main slot) or R (Acc Slot) when you have selected a hotkey to activate it (either ALT, Shift or CTRL, whichever you chose) OR, just click the Salvation icon, then press either E / R.
To use it on yourself in a group or solo, you can either click on your character or monster once you have selected the heal charm and Salvation is activated.
Pure attack solo'er: Barb / Fighter = Retribution / Powerstrike (1 class ability and 1 off class ability), Note: not too great on Intelligence, so not great at healing (Salvation) unless you allocate points to Intelligence... hence some reservations from others.
I myself use Guardian feeder, but I do use Salvation on all classes.
