Mouse-over Macros with alt based self casting

[Carni]

In case the title is unclear, here is what I'm after.

A macro that allows me to mouse over people cast my spell, and then other wise use the spell on myself without the mouseover. Possibly using a shift modifier if at all possible. Is this possible? Because if it is I can't seem to figure it out. Here is what I have so far.

#showtooltip Hand of Freedom
/stopcasting
/cast [@mouseover] Hand of Freedom
/cast [mod:shift][@player]Hand of Freedom

Naturally It doesn't work. I've also tried having the mouse over part be the shift modifier which didn't even seem to work at all. Any suggestions?

#showtooltip
/stopcasting
/use [mod:shift,@player][nomod,@mouseover][@player] Hand of Freedom

Shift: cast on you
otherwise on mouseover
if no mouseover exists, on you again

I love you. You have no idea how many other macros this will help me to create. Thank you very much.
