The Set Dictionary Value action (v8+) takes dictionary name and a key name and allows you to set the specified plain text value, by either typing in the text field, or selecting a Token.

The Dictionary name, Key name, and value can all contain text tokens, allowing a wide variety of uses. You can turn off token processing for the value field to make it easier to include backslash or percent characters.
