Command completion in mathematica : suggest rules/options

Question

In current version of Mathematica these keyboard shortcuts are quite handy

Ctrl+K completes current command

GraphPl -> press Ctrl+K  -> GraphPlot

Ctrl+Shift+K completes current command and adds argument placeholders which could be replaced with actual values with tab key

GraphPl -> press Ctrl+Shift+K  ->  GraphPlot[{vi1->vj1,vi2->vj2,...}]

However I couldn't find any keyboard option to show associated settings/options

For instance Say If I need to plot a graph with different layouts, I know I need to set Method with one of these Possible settings

• "CircularEmbedding"
• "RandomEmbedding"
• "HighDimensionalEmbedding"
• "RadialDrawing"
• "SpringEmbedding"
• "SpringElectricalEmbedding"

Two things

First How to autocomplete these options , is there any shortcut key ?

GraphPlot[sg, Method -> <what keyboard shortcut to display all possible options>]

Second how to generate following PopupMenu list programmatically

  list={
   "CircularEmbedding"
   , "RandomEmbedding"
   , "HighDimensionalEmbedding"
   , "RadialDrawing"
   , "SpringEmbedding"
   , "SpringElectricalEmbedding"
   }
Manipulate[GraphPlot[sg, Method -> m], {m, list}, ControlType -> PopupMenu]

Is there any way to introspect Mathematica functions and access method Metadata similar to the way it could be done in other programming languages, Like using reflection in Java ?

Answer 1

I don't believe there is any included function to auto-complete a string. I also cannot recall a way to view all valid settings for a particular option, other than searching the help files.

You can expedite input with the Options Inspector settings InputAliases and InputAutoReplacements, allowing entry by EsctxtEsc or txtSpace.
