macro for canceling aura with modifier

[tyip0217]

Hi, I was looking for a macro to cast a spell that gives a buff to myself, and if I hold on a modifier it will cancel the buff
for example, for use with dk's Blood tap and hunter's deterrence

I'm currently using 1 button for casting the spell and 1 button to cancel with the macro /cancelaura Deterrence, was thinking if possible to merge it in 1 button

Not levelled either of those high enough, but there is a /cancelaura spell command.
It is used sometimes by warriors for a quick way out of bladestorm with the following (I think from memory).

/cancelaura Bladestorm

You could try a /cancelaura and /cast or /use macro to have both on a single key which is basically a toggle, first trying to remove the buff should it be present, then using the ability.

/cancelaura Deterrence
/use Deterrence

Note, that is untested by myself.

Let's say your deterrence is bound to the button "G"

/cancelaura [modifier:alt] Deterrence
/cast Deterrence

Press G to deterrence
Press alt-G to cancel it.

You may replace "alt" with "shift" and "crtl".
Tried and tested.

just try something like
#showtooltip buff
/cast buff
/cancelaura [modifier:shift] buff

klicking normal will cast the buff.
klicking with shift will cancel the buff once, and if you klick with shift twice it will recast the buff.

sorry im getting drunk so i might write wrong

Let's say your deterrence is bound to the button "G"

/cancelaura [modifier:alt] Deterrence
/cast Deterrence

Press G to deterrence
Press alt-G to cancel it.

Tried and tested.

Actually it has the same effect of

#showtooltip (optional)
/cancelaura Deterrence
/cast Deterrence

The diference is that using this code you dont have to hold alt.
This code also works for Ice Block, Divine Shield and others.
