Another healing macro (!)

Ok my druid's HoTs are not totally up to the job in an instance, so with that in mind I need some help.

My normal setup is F1-F5 toss a /castsequence on the party member:
F1:
/target party1
/castsequence reset=combat/target/5 Lifebloom, Lifebloom, Lifebloom, Rejuvenation, Regrowth, Healing Touch

Now this isnt fast enough to get to the direct heals when I really need them, so I was wondering how I could incorporate Nature's Swiftness into this macro?

Could I do a shift+F1 that will do:
/cast Nature's Swiftness
/cast Healing Touch

I'm just unsure how to mod that so it will all be one macro button.
My guess is that:
/target party1
/cast [mod:shift] Nature's Swiftness
/cast [mod:shift] Healing Touch
/castsequence [nomod] reset=combat/target/5 blah blah

doesnt work, though honestly I havent tried it. If I remember right 2 /casts in a row do not work.

Anyone have a solution?

This is how I do healing (I have 1x unholy, 3x frost, 1x resto druid)

keys 1-5 (I use a custom keyboard so the keys are just an example)

/castsequence [nomod, target=toona] reset=7 Rejuvenation, Lifebloom, Lifebloom, Lifebloom, Regrowth
/cast [mod:alt, target=toona] Swiftmend
/cast [mod:shift, target=toona] Nature's Swiftness
/cast [mod:shift, target=toona] Healing Touch
/cast [mod:ctrl, target=toona,nodead,help] Regrowth
/cast [mod:ctrl, target=toona,dead,help] Rebirth

etc etc for toonb-toone

Interesting, so that takes care of Nature's swiftness and the heal in one button push? Or do you have to hit it twice?
edit: nm tested it :D
