Being an Oak who has from time to time shielded an angel in the heat of combat or taken that extra 1/2 second trying to target myself and dying, I would like to see a couple of buffs activated by hitting their hot key a second time.

The first time you push the key it would work as it does now, a targeting cursor would appear and you would cast the effect on whoever you mouse-clicked on. If you pushed the hotkey a second time while the targeting cursor was active, the following effets would automatically be applied to your demigod. Oak-shield, Sedna-heal, QoT-bramble shield. In addition, if you hit the mulch key a second time as QoT, the weakest shambler active would be mulched.
