               Set the zoom level: the font size will be multiplied by this level. The range
-              is from -4 to 4, default is 0. Each step multiplies the size by 1.2, i.e.
-              level 4 is 2.0736 (1.2^4) times larger than the default size.
+              is from -7 to 7, default is 0. Each step multiplies the size by 1.2, i.e.
