Greetings;  
As shown in the attachment, I tried to use names, names! and I tried [SHIFT]? to find keywords/functions . What is the correct keyword or script to view all keywords and their “docstrings” ?  
As shown in the top half of the attachment, I am guessing and researching online what units of measurements are valid. By the way, I am using [Replit.com](http://Replit.com) and it has Julia 1.3.

`varinfo()` or `names()` shows the objects but not their docstrings.

```julia
 Pkg.add(["LinearAlgebra","Unitful","CSV"])
using LinearAlgebra
using Unitful
using CSV

names(Unitful)
varinfo() 
help?> u*

```

It seems that varinfo() provides the local variable information, not the variables or units of measurement found in the added package. I tried the Unitful.jl, CSV.jl and LinearAlgebra.jl packages. When I use the names(EnterPkgName) and [SHIFT] ? I get some function info,but the docstring info did provide some hints of extra units of measurement are J for Joule, N for Newton and m for meters.

I don’t think there is a way to do what you want.

Maybe this is something that should be easier, but I think most people just refer to the online documentation.

Here is a solution using Documenter

```julia
julia> julia> using Documenter, Markdown, DataFrames;

julia> for n in names(DataFrames)
           docs = Documenter.DocSystem.getdocs(n)
           Markdown.MD(map(Documenter.DocSystem.parsedoc, docs)) |> display
       end;

```

This particular example might be overkill, of course, but I could see how a similar functionality might be more useful in other contexts.

You can write `Module.<tab>` to get a list of symbols, exported and not. Or you look up the docs and/or source online.

Greetings;  
Thank you for the useful script in which I replaced names(Documenter) with names(Unitful), besides other word replacements / additions.

```julia
import Pkg;
Pkg.add(["Documenter","DataFrames","Unitful","Markdown"]);
using Documenter, Markdown, DataFrames, Unitful
for n in names(Unitful)
             docs = Documenter.DocSystem.getdocs(n)
             Markdown.MD(map(Documenter.DocSystem.parsedoc, docs)) |> display
         end;

```

It did provide more insight, but not the Units of Measurement list (ex. hr, s, N, m, kg, inch,W, V…). I am viewing the documentation,

and testing assumed Units of Measurement .

[Here](https://www.github.com/PainterQubits/Unitful.jl/tree/master/src%2Fpkgdefaults.jl) is the definitive list of units defined in Unitful.

Thank you! The lesson I learned from you was to look at every file and folder in documentation to find my answer.  
I posted the results just in case github is down…
