An Eaction Guide? Crossbars?

[Gardes]

You're thinking of making one button press having 2 different actions, correct? The /chotbar change I mentioned will work but it's very sensitive since one button press will activate the /chotbar change command regardless of whether the actions above it activated or not, so gcd might screw things up for you if you press the macro too early.

mbio [placed on set1]
/micon Bio
/ac Bio <tt>
/ac Bio <t>
/chotbar change 2

mbio2 [placed on set2]
/micon "Bio II"
/ac "Bio II" <tt>
/ac "Bio II" <t>
/chotbar change 1

Now, I cant vouch for this but try adding "/wait 1" right above "/chotbar change x". It'll delay the change and count until 1 second after your last macro press (the previous macro mashes orders are replaced by the latest) before changing. Should give you some lee way but I can't guarantee it will be suited to your needs.

/ac Provoke <t>
/wait 1
/p [Provoke] [Just used it] <se.1>

I've recently used that for my announce macros. I can mash it in a hurried situation and the party chat would only see 1 line of it instead of being flooded by [Provoke] [Just used it] <se.1> as many times I mashed it (I like mashing).
