No. I want one hot key (or macro) that has multiple different responses behind it in a round robin fashion.
Keep it fresh for customers. When they are regular users of chat support they see the same responses over and over. It begins to be impersonal to them after time and they get annoyed that it seems robotic.
For example I can create a macro that says "I’ve just picked up this ticket up, and I’m reviewing it now. I’ll get back to you shortly with an update." but I can also say a bunch of different responses and have it mean the exact same thing but not look robotic to the user.
"This is on our radar now — I’ll come back to you shortly with an update."
"We’re on it now and will get back to you once we’ve reviewed the details."
"I’m taking a look now — I’ll follow up in a little bit."
"I’ve just started looking into this and will be back in touch shortly with an update."
"Thanks for your note — I’m reviewing this now and will follow up shortly with an update."
