There's really a much easier method than what you're trying to do and it's called following standard procedure :P

http://isboxer.com/wiki/Quick_Start_Guide_40#Part_4:_Gameplay_as_a_multibo xer

So first of all, instead of broadcasting everything under the sun just follow the recommended method and use Many New Mapped Keys to map the keyboard keys you actually need to broadcast. http://isboxer.com/wiki/Common_modifications#Hotkeys (Note that this link is generally for games other than WoW and uses "Combat" key map where you have a "FTL DPS Keys" key map)

Secondly, if you would like to set up certain areas of the screen to broadcast clicks, like over certain Action Bar buttons, set up Repeater Regions over those areas. http://isboxer.com/wiki/Common_modifications#Clicking


This way you leave broadcasting alone, you don't blacklist anything so you're not prevented from actually broadcasting something when you need it, you keep the full functionality of your mouse, and the keys you want passed are passed. "But Lax, that means I have to make a Mapped Key for EVERY SINGLE KEY I WANT TO SEND>!?!?!!/11/1?" -- *YES*, and it is quick and easy to do using Many New Mapped Keys, as linked. Note that you don't actually need a mapped key for every single thing, because you can still turn on broadcasting for those rare moments when you need to cast Super Discombobulate or whatever it is that you didn't make a Mapped Key or Repeater Region for. Even if it requires right clicking. You only need to map the things you need instant access to, like during heated combat.



So.... to answer your questions...
1. To change your Repeater Hotkey, don't set it to Del under your Repeater Profile, thats why you're having a problem. Instead, in the top left pane under Key Maps select Control, then in the bottom left pane select Activate Repeate and set THAT hotkey to Del.

However, one thing you're NOT going to be used to from Keyclone is that there is actually two "broadcasting modes".... the 1 to 1 broadcasting mode that you're trying to match your old config to, and Key Maps which do specifically what you tell them to. Disabling broadcasting does not disable Key Maps.

Still recommending the standard procedure.

2. If you're that keen on disabling Mouse2, do it with a Mapped Key. All you need is one that has the Hotkey configured to Mouse2, and you can specify what it should do. If that's nothing, then your Mapped Key doesn't even need an Action in it. But you could also set the Mapped Key to have the "Hold" option enabled, and a Keystroke Action to send Mouse2 to Window:Current. This would make it only go to the current window, even if Broadcasting is enabled.
