Using texshow-web

Point your webbrowser to the default location of texshow-web (http://texshow.contextgarden.net) to get a list of all commands for the english interface (en). Click on a command to see its descripton. You can also invoke texshow-web with a parameter (e.g. ...contextgarden.net/about) to display the description for a specific command.

How to read the syntax description

Let us examine the following example:

\placefloat[...][ref,ref,...]{...}{...}
[...]	left right here top bottom inleft inright inmargin margin leftmargin rightmargin leftedge rightedge innermargin outermargin inneredge outeredge inner outer regel high low fit page opposite always force tall reset line height depth
[ref,ref,...]
{...}	text
{...}	text

You would not type \placefloat in your TeX-text, but rather a previously defined kind of float, figure for example. So the command would be \placefigure. The first two arguments of \placefloat are optional (red color), the second two are mandatory. The first argument takes one of the mentioned keywords. If not given, it uses the one in bold: here. ref stands for a reference, just insert a name that you want to refer to later. The third and fourth argument don't take the keyword text, since the word text is in italic. They can contain any kind of text.

filter and searching

There are several possibilities to find your favorite ConTeXt command. The most simple one is just look in the left frame of texshow-web and choose from the long list. To shorten the list, you can either use the filter or the search function. A filter just restricts the number of commands displayed in the left frame. The search method looks through all descriptions and displays the matching commands. Both the filter and search field take simple texts as their input. Here are some examples:

col
matches \color, \column, \comparecolorgroup, \setupcolors and alike
(the empty string)
matches everything. So just delete the characters in the textfield to get all commands

editing the descriptions

If you want to add something to the description of a command, please don't hesitate and do so. You can't break anything, you can rollback any time later. The syntax you can use in the edit field is the same as the mediawiki wiki markup with the following exceptions: you cannot use the pipe table syntax. See the help page on the wiki.

history (version control)

All comments, descriptions and syntax changes you enter in texshow-web will be saved in a special way, so that you can retrieve old revisons. Just click on 'view history' below the edit box and you will see the older revisions. Click on any of those links to see its contents.
