But for the fifth, while there is a modifier "chat", those macro does not open the chat menu.
I went through all of the available arguments and there are more than one that are not working as expected. I have submitted a problem report into the system on this issue.
For the menu bar buttons Help and <?> (Codex of Wisdom) i couldnt find a modifier (nor another macro).
I also submitted a problem report into the system on these two as well as several other options that should be available.
But i couldnt find an option to change the text color within that PartyChat window from nearly unreadable dark blue to a more eye friendly color.
I confirmed this issue and although you can adjust the font used for this window, you cannot adjust the text hue. I have also submitted a problem report on this issue.
