Clickbar issue

[MiRai]

Now since this is the first time that i'm trying this.. how can i make it work that the clickbar icon is showing on the target that i want to heal?

I checked this streamer out SerScruffington, and he really had a nice setup for this. He clicked on a toon that needed healing, the icon showed up on that target and was healing that specific target.

If a healing icon shows up on the unitframe, then that could just be how his unitframes work - This is an option for some unitframes, after all. ISBoxer doesn't know what's going on, in game, so even if you were to create such a setup, there's no guarantee that the healing spell was properly applied to the target, even if you configured an icon to appear.

So, are you sure that it's an ISBoxer thing, or is it part of his unitframe add-on? You might want to ask him the next time he's streaming.

is there an action possible when you click on the icon that some keymap with multiple steps, resets?

If you want to adjust the step of a Mapped Key, then the Mapped Key Step Action I linked to in my previous reply addresses that exact need. If you want to reset a multi-Step Mapped Key to Step 1, then use the MK Step Action to do that. On the other hand, if you need specific help with something in your profile, then share it and explain what you'd like to adjust, otherwise I can only speak in general terms.
