Scroll up;<y1>;<y2>;<delay>[;fadeawayheight]
Scroll down;<y1;<y2;<delay>[;fadeawayheight]
Banner;<delay>[;<lefttoright=0/1>;fadeawaywidth]

Style Modifiers:

\n						soft break (only valid with \q2, gets replaced with soft space in other wrap modes)
\N						hard break
\h						hard space

Between {...}:

\b<0/1/weight>					bold
\i<0/1>						italic
\u<0/1>						underline
\s<0/1>						strikeout
\bord<width>					border
\shad<depth>					shadow
\be<0/1>					blur edges
\fn<name>					font
\fs<size>					size
\fsc<x/y><percent>				scale
\fsp<pixels>					spacing
\fr[<x/y/z>]<degrees>				rotation
\fe<charset>					character set
\c&H<bbggrr>&					primary color
\<1/2/3/4>c&H<bbggrr>&				primary/secondary/outline/shadow color
\alpha&H<aa>&					primary alpha
\<1/2/3/4>a&H<aa>&				primary/secondary/outline/shadow alpha
\a[n]<alignment>				ssa alignment type (n - numpad layout)
\k[<f/o>]<duration>				karaoke (f - filled from left to right, o - outline highlighting)
\K						same as \kf
\q<0-3>						wrap style (0,3 - even lines, 1 - endofline, 2 - manual)
\r[<name>]					loads default (or <name>) style

\t([<t1>,<t2>,][<accel>,]<style modifiers>) 	animation, accel: 0->1 slowing, 1->.. accelerating

\move(<x1>,<y1>,<x2>,<y2>[,<t1>,<t2>])
\pos(<x>,<y>)
\org(<x>,<y>)					changes the origin of the transformations (scaling, rotation), always use \pos instead of \org to manually position the subs
\fade(<a1>,<a2>,<a3>,<t1>,<t2>,<t3>,<t4>)	fadein: t1 -> t2, fadeout: t3 -> t4
\fad(<t1>,<t2>)					fadein: start -> start+t1, fadeout: end-t2 -> end
\clip(<x1>,<y1>,<x2>,<y2>)			clips drawing outside the given rectangle
\clip([<scale>,]<some drawings>)		clips by intersecting with the drawn shape

Drawings:

\p<0/1/..>					turns on/off drawing mode (0 - off, 1.. - on)
\pbo<y>						baseline offset

Between {\p<1/..>} and {\p0}:

m <x> <y>					move to 
n <x> <y>					move to (doesn't close)
l <x> <y>					line to
b <x1> <y1> <x2> <y2> <x3> <y3>			bezier to
s <x1> <y1> <x2> <y2> <x3> <y3> .. <xN> <yN>	b-spline to (uniform)
p <x> <y>					extend b-spline
c						close b-spline
