This time with a few modified screenshots to demonstrate how I would like to see this feature implemented in keyclone.
First, a (modified) screenshot of how the new keymap editor part would look like with deactivate mouse coordinates:

Second, a screenshot (also modified) of how the same part would look like, with activated mouse coordinates:

Now a screenshot of my Warrior ingame with two possible uses of this coordinate-thingy:

(a simple empty macro just to have an icon and the grid-(files.wowace.com)-display)

You see the red marked areas, these could be the possible areas you would define in keyclone and than ingame just click on one of these red marked areas to send the hotstring "heal.damn.it" which would be sent to your heal-toon who got "heal.damn.it" on the key "1" and et voila - a fine renew ticking on your hopefully not so badly injured warrior!
And if you're playing a tanking class you could also define these areas bound to mouse button 2 instead of one, this way you easily could heal yourself / others with the right mouse button but still would be able to select them for other purposes with the left mouse button.

Now, how about it? I think I can't make it more simple to demonstrate.
