Shadower key configurations.

I'm weird: I use my index finger for the primary mob skill and use my ring finger to jump :c

z: Single target (savage blow)
x: (movement skill- Flash jump)
c: Mob skill (primary-BoT at the moment; change to Boomerrang after 4th job)
v: regular attack
a: Mob skill (secondary, but right now it's housing darksight)
s: Buff (Meso Guard)
d-g: (random skill/ buffs- pickpocket, shadow partner, etc)
q: mount usually, but right now nothing
e-r: random skills

Shift: jump
Ctrl: loot
Alt: Assaulter
Space: haste

Del, Pgdn: primary pots (hp/mp)
inst, home: booster and self HB (respectively)
pgup: more pots (usually something that heals both Hp and Mp like NLC pizza or ginger ales)
end: primary self heal (chakra)

Random keys on my keyboard also house random skills like L7 and steal and double stab. I also place chairs on the right side of the keyboard.

I do the same with my Buccaneer cause they have just as many skills. I tend to follow the same build for all my characters.
zxcv line is used for non- transform, non energy charge attacks (primary skills)
asdf line is used for backspin (a) and energy skills
qwer line is used for transform only skills and the mount on (q).
