Came across this in the wiki but doesn't seem to work.

[sp000n]

I made the following macro:

"/assist [mod:ctrl,mod:shift,nomod:alt]Ovii;[mod:ctrl,mod:alt,nomod:shift]Ova;[mod:alt,mod:shift,nomod:ctrl]Ovae;[mod:ctrl,mod:alt,mod:shift]Ovoe;[mod:alt,nomod:shift,nomod:ctrl]Ovie"

Then I drug it to my ActionButton0. When I press CTRL+SHIFT+0, however, it does not assist Ovii. Can you spot the problem with this setup?

/points at Sp00n!

Just kidding. :P

You might make sure you don't have any other keys bound to what you are trying to use for this. If CTRL+SHIFT+0 is already set to cast fireball (for example) on bar 4, then it won't work for this macro.

A fair guess... but there's no result when I mouse-click with the modifier keys held down. I've also checked my keybinds. The button is most definatley being pressed.

hm, may I ask, for what you need this macro? typical it looks like an ftl-macro, which never would be activated by simply pressing 'CTRL+SHIFT+0' yourself.

Anyway, the typical problem here is, as mentioned above, that any combination like 'ctrl+0' or 'shift+0' is bound to another action and thats why the macro isn't activated.

You can use the Bindings Reminder addon to be sure of it.

Just install it and type "/br show" and a keyboard will pop up. Over the mouse on a key and it will show any action bound to that key (with every possible modifier).
Pretty damn useful, if you ask me.
