OK, placing Ground Markers works fine.
Thank you
SDPhantom, you saved my addon
I have a specific icon to delete placed ground marker, so I don't use the right-click on marker's button.
But I used shift to trigger another macro (insert marker's icon in the opened chat box, but "/sit" to simplify in the following example:
Lua Code:
button:SetAttribute("shift-macrotext1", "/sit")
This code is no longer working. Can you tell how to add a shift-clic macro to your code?
