+			<p><pre>As of June 25, simple expressions should work. Some examples:
 
-			An example would be p[x,y].r = <b>(x + y) == 100 ? 255 : p[x,y].r</b>
+			p[x,y].r = <b>(x + y) == 100 ? 255 : p[x,y].r</b>
 
 			This sets all red pixels to the same value as the input, except those pixels
 			that form a diagonal line where x + y == 100, and those pixes are converted to white.
 
-			Another example would be p[x,y].r = <b>p[x,y].g</b>
+			p[x,y].r = <b>p[x,y].g</b>
 
 			This sets all the red pixels to the value of all the green pixels.
 
-			One final example would be p[x,y].b = <b>p[y,x].b</b>
+			p[x,y].b = <b>p[y,x].b</b>
 
 			This rotates the blue component 90 degrees.
+
+			p[x,y].g = <b>(p[x,y].g*3 + p[x+1,y].g + p[x,y+1].g)/5</b>
+
+			This performs a simple convolution operation on the green pixels.
+
+			p[x,y].t = <b>((x == y) || (x == (width - y))) ? 0 : p[x,y].t</b>
+
+			Sets the transparency to fully transparent in an x shape.
+
+			p[x,y].s = <b>(p[x,y].r == p[x,y].g) || (p[x,y].r == p[x,y].b)</b>
+
+			Sets the selection to any pixels where the red component equals either
+			the green or blue component

 			<p>Still to be done is expressions with inequalities, expressions with && and || clauses,
 			and a bunch of other fixes.</p>
