The Mapped Key "A_Assist and Engage" as well as the Mapped Key "Z_Assist Me" don't have the "Hold any Keystroke Actions while Hotkey is held" enabled. For LOTRO this is required if ISBoxer wants to send a keystroke with a modifier to the game. In the Alt+T example only T will get send to the game ... which opens the crafting window per default.
That is because all the Z_Commands are coming from something else....in this case A_Assist and Engage (F Key) is PRESSED OR RELEASED....meaning it is Executed Twice!!
That means Z_Assist Me....which has 2 Steps....executes Step 1 on the Press of F and again when Released. If you QUICKLY (less than 100ms is what I found) tap the F Key the Assist May Not work....Slow Down and Press then Release. Works every time.
By the Way....the Default LoTRO Assist is F (No Modifiers)....ALT+F# keys Assist Particular Group Members but this does not work at this time....I remember it working a long time ago but not now for some reason.
This is done Automatically with the F Key Release (Step 2): To get the Combat Mode working properly simply press U for Use Object and the Auto Attack will start (enter combat mode). This is also the Default Universal Interaction Key for most things (Delete for Items and Resource Nodes)
Manual Sequence for LoTRO Assisting:
F# for Group Member
F for Assist
U for Use
So if you press F2 then F everyone will Assist and Follow/Use/Combat the Target of F2....same goes for F3 and F4
ISBoxer LoTRO Configuration:
F Press Step 1: Select Self (F1) so that companions will not be targetted
F Release Step 2: Select Currently Active Window, Assist the Active Window, Use the Object/NPC Targetted.
So basically 1 button doing 2 steps.
