For those that don't know there is an addon for wow called Healbot. It is a raidframe addon that allows you to cast spells/abilities on group members by simply clicking on their name. You can set spells to any combination of shiftf/ctrl/alt + any mouse click. Shortly before I quit playing FFXIV I decided to see if there was a way to emulate this functionality and came across a program called X-mouse button control. While it's functionality isn't as smooth as an official addon, it can be used along with in-game /mo macros to the same effect.
It took me several hours to set up properly, but once it was I was able to have all my SCH spells set to cast with mouse clicks. I had to assign a full hotbar to F1-F12 and make a macro for each spell that included /mo targeting. I then assigned the F1-F12 keys to various combinations of shift/ctrl/alt+clicks (nothing assigned to normal left click as this is used for targeting party members when needed). You can also set up another key press to toggle the whole thing off/on so you can interact with objects/npcs normally if you choose to map normal right click.
This setup allows for quicker response time in healing/curing debuffs since you don't have to waste time targeting the party member and pressing a # key. It also frees up your main action bar for medica/succor/buffs/debuffs/DPS spells, etc. I set this up shortly before the addition of fairy macros and came across a great trick with the setup. I could set embrace to a F# key from the pet ability menu and then set a /mo physick macro to another F# key and then have the program "press" both when i right clicked, effectively allowing me to cast both spells on a single click. However since there were no /mo macros for the fairy i could target the MT, right click another member, and I would physick the other member while my fairy embraced the MT. This was very reminiscent of the Holy Paladin's Beacon of Light from WoW, which i loved.
To wrap up, this isn't doing anything that you couldn't do within the game if you had one of those expensive 12+button mice. And now that you can set up fairy macros you could very well set up something similar to the physick+embrace trick by setting specific targets in your macros. This just allows you a bit more flexibility and doesn't require you to constantly switch up macro target lines or have multiple macros set for the same spells.
*Small Warning* If you choose to mess around with this program, you might want to turn off it's automatic startup when you turn on your machine. Also, you should never change normal left-click. During setup I accidentally changed it and was unable to do anything with my mouse. I had to spend a good 15 mins working around the crappy dropdown lists with tab and the arrow keys.
Edit: Sh*t click.. lol
