.if !\n(xx .so tmac.e .SH Options .PP Each instance of the editor has a set of options, which can be set to tailor it to your liking. The command .I edit invokes a version of .I ex designed for more casual or beginning users by changing the default settings of some of these options. .PP There are three kinds of options: Boolean, numeric, and string options. Options are controlled by the .I set command which can be used to show their current values or to assign new values. The options, their defaults, and a short description of each are given in the following table. A more complete description of each option will be given near the end of this reference manual. .TS box; c s s s c | c | l | l lI | lI | l | lR.
