hm so if i set a macro to "K" and have that cast sequence i need to hold down ALT button the whole time?

so on bar 1

corruption,curse of agony,immolate (wheres Drain life go) [lock]
fireball [mage]

im still completely clueless

i push K and on the lock it will cast dots then spam drain life and on the mage it will spam Fireball?

i have that atm but not binded a key because all it does is cast Corruption then thats it just stops
