Low-Level System Spelunking

The Wolfram System is a large and complex software system. Although strongly not supported for production purposes, it is sometimes instructive to "spelunk" in the system, looking at low-level organization and obscure features.

(RefLink[Names, paclet:ref/Names]) — complete lists of symbol names matching a pattern (e.g. "*`*")

(RefLink[Contexts, paclet:ref/Contexts]) — give complete lists of contexts for symbol names

(RefLink[SystemOptions, paclet:ref/SystemOptions]) — low-level system options

(MenuGrayLink[Show Expression, paclet:ref/menuitem/ShowExpression]) ((Key2[shift, ctrl, e])) — show the symbolic structure of notebook contents

(MenuGrayLink[Option Inspector, paclet:ref/menuitem/OptionInspector]) — inspect lists of front end options

(RefLink[Options, paclet:ref/Options]) — get a complete list of options for (RefLink[$FrontEnd, paclet:ref/$FrontEnd])

(RefLink[Trace, paclet:ref/Trace]) — trace every step in the evaluation of an expression

(RefLink[Stack, paclet:ref/Stack]) — show the state of the complete evaluation stack
