I would suggest trying Rob/Keyclone/Tiny's page.

Most of the people on this site seem to have moved to either IS Boxer or HotKeyNet (if you're willing to do/learn your own scripting).
I haven't used Keyclone in four or five years.
I do like how it is infinitely re-bindable to any one computer you ever own.



IS Boxer has so many features that I would suggest at least taking a look at.

Keyclone is great for straight key broadcasting (and even whitelist certain keys to only broadcast, or blacklist certain keys to never broadcast), but I would essentially have to put an ability on '3' for two of five characters but none of the others, then broadcast '3' to everyone.

With IS Boxer you have mapped keys.
These are hot keys which do a multitude of things.
You can have multiple steps, where it does one thing on the first press and another on the second press (infinite steps, if you like) and it loops back to the first step after the last has completed; you can prevent it from advancing to the next step (no matter how many presses of your hot key) for a duration and have it reset to the first step after 'x' seconds from either first press or most recent press.

Mapped keys can have variable targets...
You can target 'Current Window' or 'All Without Current' (everyone else).
You can target an 'Action Target Group', which is a predefined set of characters... such as everyone with a mouse click targeting circle or all your healer capable toons (in the case of a 1x Tank / 1x Dedicated Healer / 3x Druid/Paladin/Shaman DPS).

In the case of actions not on the Global Cool Down, such as your Interact With Target hot key (within WoW), you can have a mapped key automatically send that to your melee characters in addition to sending your main keybind to the targets of your choice.

That's just looking at mapped keys, and not everything they can do.



Clickbars/Menus allow you to mouse click an icon on your screen, and have it execute a mapped key.
So you don't have to necessarily keyboard activate everything.

You can have a truly massive variety in window layouts.
One example is full screen stacked, where everything is full screen with each on top of each other.
Then, just like PiP swapping, you can determine which window is on top.
You can create 'Viewers' to see the important information from your other windows.

Your mouse can automatically enable mouse broadcasting, when it enters a viewer or a mouse repeater region on your screen.
That includes broadcasting modifiers, such as Alt + Left Click or Ctrl + Right Click, if you like.
The mouse broadcast disables when it leaves your region/viewer.

Swapping between clients (with Instant Swap enabled) literally is instant.
With KC, there was a bit of a delay.

Mouse broadcast is instant and in real time.
You can see the target circle moving on your other windows (example Mass Dispel or Blizzard or Rain of Fire or Hurricane), as you move the mouse on the main window.
They all click in each window at the same time.
You can have the mapped key enable mouse broadcasting for your toon's with mouse-click target abilities (the Action Target Group), when you click/press the hot key for that ability... without activating it on the other windows (so your Tank or Healer) doesn't also enable broadcasting and then run somewhere that you click.
The mouse broadcast turns off after the click.

You can run a 'Pro Configuration'.
This is virtualization of mapped keys, where the key is translated into the appropriate spell/ability for a given character type.
That way you can basically mix and match your toons as much as you like, without modifying your configuration, and have it work perfectly.

IS Boxer supports five computers on the one subscription.
With as many clients on each system, as your computer can handle.
There are wizards for almost everything, getting you a very functional setup for most games.

IS Boxer will work with just about every game out there.
There is a lot of support for it, including an IRC on the IS Boxer site.
Lax gives phenomenal support, and the community often takes the time to help as well.
MiRai (you might remember him as Fenril) has a ton of very much amazing videos on IS Boxer too.

It's definitely worth taking a good look at.
