Editing Quartus settings file

I am editing some assignments through my Quartus settings file (.qsf). I found MNL-Q21005 (Altera Quartus Prime Standard Edition Settings File Reference Manual) which shows all of the possible assignments. However, in many cases, this manual is missing the possible values that can be used to set the assignments. For example "POWER_PRESET_COOLING_SOLUTION" simply lists the type as "string". How can the possible values be found? Is there some TCL command window I am missing with auto-complete that gives me options as I type?
