IWT: What you've shown us looks correct (apart from the last image - you don't want to set the Hotkey in ISB42 - Party). As a general rule, you only set Hotkeys on Key Maps with "Hotkeys" in the name. You may need to share your ISBoxer configuration for further assistance. Please supply the name of the Character Set you are using and describe any actions that do occur when you press X.

IWGO: You cannot macro this. The standard method is to use mouse broadcasting (Shift+Alt+R toggles it by default), possibly in combination with a SetView macro. Given that your slaves will be behind your main it may require two clicks.
