because IS_MSL packets can not be used for commands, I would need to use IS_MST. But these messages can be seen on other hosts. So does anybody know, if this is also true for commands?
E.g. if I want to assign a text to the Ctrl+F6 Button on my keyboard, so I need to send a IS_MST packet with /ctrlf 6 text. I want to make sure that other clients are not affected by this.

thx and regards

No, it won't be sent to other clients.

A /i message is not seen by the others, so I use this on my host for commands. This is the ISP_III package.
