On the Code Assist Preference Page the auto completion trigger characters are defined. Normally it should not be necessary to change these values.

By default the editor suggests a list of already used variables when the characters $ @ % are typed. To switch this feature off, deselect the Inspect Variables check box.

The External content assistant field allows advanced users to specify a custom Perl script to be used to generate autocompletion suggestions, for example to integrate project-specific suggestions or AI language models (see the section called “External Content Assistant”)).
