Editing WoW:SecureActionButtonTemplate (section)

==Button remapping==
SecureActionButtons are also able to change the button being clicked in response to whether your target can be assisted ([help]) or attacked ([harm]) by you; the two relevant attributes are "helpbutton" and "harmbutton". The value of those attributes, should they match, will be used as the button to resolve the "type" and other required arguments.

For example, suppose we wanted to create a button that would alter behavior based on whether you can attack your target. Setting the following attributes has the desired effect:
{| class="darktable"
!Attribute !! Value !! Purpose
|-
| "unit" || "target" || Make all actions target the player's target.
|-
| "*harmbutton1" || "nuke1" || Remap any left clicks to "nuke1" clicks when target is hostile.
|-
| "*harmbutton2" || "nuke2" || Remap any right clicks to "nuke2" clicks when target is hostile.
|-
| "helpbutton1" || "heal1" || Remap unmodified left clicks to "heal1" clicks when target is friendly.
|-
| "type" || "spell" || Make all clicks cast a spell.
|-
| "spell-nuke1" || "Mind Flay" || Cast Mind Flay on "hostile" left click.
|-
| "spell-nuke2" || "Shadow Word: Death" || Cast Shadow Word: Death on "hostile" right click.
|-
| "alt-spell-nuke2" || "Mind Blast" || Cast Mind Blast on "hostile" alt-right click.
|-
| "spell-heal1" || "Flash Heal" || Cast Flash Heal on "friendly" left click.
|}

If the button is remapped by the "harmbutton" or "helpbutton" attributes, the value of the "unit" attribute is reevaluated with the new button suffix: it is therefore to make a button that would check the hostility of one unit, and perform a reactive action on an entirely different unit.
