Echo prompts to history

Allows the command prompt to move into a command history window after use. Turn this off to see only the command name in the history window and not the prompts.

Autocomplete commands

Turns on automatic command completion when typing at the command prompt.

Use fuzzy autocomplete

When enabled, in-line autocomplete suggests the most used candidate. For example, LI most likely autocompletes to Line rather than something like LimitReferenceModel, and the autocomplete menu contains best partial and inexact matches. The autocomplete list consists of two command lists divided by a blank line. The first list contains the exact matches that start with the string you typed. The second list contains the non-exact matches sorted by how closely they match the typed string.

When disabled, autocomplete uses the first letters of the command name in alphabetical order.

Direction arrow icon

Shaft size

Sets the length of the shaft for the arrows of the Dir command.

Arrowhead size

Sets the size of the arrowhead for the arrows of the Dir and Arrowhead commands.
