Type Alias Registers

TeX registers represent "variables" and "constants".

Changing the values of some registers can modify the layout of math expressions.

The following registers might be of interest:

• thinmuskip: space between items of math lists
• medmuskip: space between binary operations
• thickmuskip: space between relational operators
• nulldelimiterspace: minimum space to leave blank in delimiter constructions, for example around a fraction
• delimitershortfall: maximum space to overlap adjacent elements when a delimiter is too short
• jot: space between lines in an array, or between rows in a multiline construct
• arraycolsep: space between columns in an array
• arraystretch: factor by which to stretch the height of each row in an array

To modify a register, use:

mf.registers.arraystretch = 1.5;
mf.registers.thinmuskip = { dimension: 2, unit: "mu" };
mf.registers.medmuskip = "3mu";
