[TalkAction] See all characters that are on account

[Galaxy]

Hello Otlanders !

I need a script for talkaction that will do the following:

GM says: /charlist player_name
now a window pops out on GM's screen (the same window when you say command /commands or just open any writeable item). And in that window there is written:

Here are all characters that are on players_name account:
Now, here is the list of the characters. For example:
Testo
Testotwo
Testothree

Thank you !
