I'm aware that one can use \tikzstyle{every label}=[...] to apply styles to every label within a tikzpicture; or \tikzset{mystyle/.style={...}} to apply style specs to a specific type of node mystyle (from this answer); however, I'm having trouble finding style specs that meet my needs, mostly because I don't know what types of options are valid TikZ and what aren't.

For example, I wanted the labels x, y, and z in the take-grant diagram below to be in bold roman type, but not the labels on the edges. It turned out that adding the \tikzstyle{every label}=[font=\bfseries] was what I needed, but it took a lot of mostly fruitless searching before I found that. Is there a concise resource which lists all of the style specs one can use?

More generally, although the TikZ manual gives lots of thorough examples of using options for nodes, paths, and styles, it does not appear to be comprehensive. Am I missing something? Are there better resources for enumerating options in general?

\documentclass{article}
\usepackage[utf8]{inputenc}

\usepackage{tikz}
    \usetikzlibrary{arrows,topaths}

\begin{document}

\begin{tikzpicture}[>=stealth',semithick,auto]
    \tikzstyle{subj} = [circle, minimum width=8pt, fill, inner sep=0pt]
    \tikzstyle{obj}  = [circle, minimum width=8pt, draw, inner sep=0pt]
    \tikzstyle{dc}   = [circle, minimum width=8pt, draw, inner sep=0pt, path picture={\draw (path picture bounding box.south east) -- (path picture bounding box.north west) (path picture bounding box.south west) -- (path picture bounding box.north east);}]

    \tikzstyle{every label}=[font=\bfseries]

    % Before diagram .........................
    \node[obj,  label=below:x] (xa) at (0,0) {};
    \node[subj, label=below:z] (za) at (1,0) {};
    \node[dc,   label=below:y] (ya) at (2,0) {};

    \path[->]   (za)    edge                node[swap]  {$t$}       (xa)
                        edge                node        {$\alpha$}  (ya);

    \node at (3,0) {$\vdash^{*}$};

    % After diagram .........................
    \node[obj,  label=below:x] (xb) at (4,0) {};
    \node[subj, label=below:z] (zb) at (5,0) {};
    \node[dc,   label=below:y] (yb) at (6,0) {};

    \path[->]   (zb)    edge                node[swap]  {$t$}       (xb)
                        edge                node        {$\alpha$}  (yb)
                (xb)    edge[bend left=60]  node        {$\alpha$}  (yb);

\end{tikzpicture}

\end{document}

Are you sure this is the output you get from your code? Maybe you have placed your TikZ picture inside a math environment or the text is in italics before the TikZ picture. –  percusse Jan 24 '13 at 1:21
    
Doh! I had it inside of a lemma on my end of things (which doesn't yet have any text, so I didn't notice it was italicizing everything). Edited the question and output accordingly. Though the specific problem is solved, the underlying question still remains. –  Tim Parenti Jan 24 '13 at 2:36

Related: Summary of Tikz commands, especially Andrew Stacey’s non-community-wiki answer. Also related: Should \tikzset or \tikzstyle be used to define TikZ styles? (\tikzstyle only sets /.style, there are many more handlers.) –  Qrrbrbirlbel Jan 24 '13 at 2:43

@Qrrbrbirlbel The summary of Ti<i>k</i>Z commands does indeed look useful, but in a way, is the opposite of what I'm looking for. I'm interested in a comprehensive list of options. For example, when Andrew Stacey's CW answer says draw[=<colour specification>], what counts as <colour specification>? –  Tim Parenti Jan 24 '13 at 2:52

And to hopefully minimize the confusion: \tikzstyle{<name of style>}=[<stuff>] does nothing else than \tiktset{<name of style>/.style={<stuff>}}. So you could actually apply every label/.style={font=\bfseries} to a node with labels, to a path with nodes with labels, to a scope with nodes with labels or …. In the case of the every node/.style there is even a short-cut: the nodes key. Issuing nodes=<stuff> does nothing else but every node/.style={<stuff>}. Conclusion: Oftentimes keys are short-cuts to other keys and nest deeply . –  Qrrbrbirlbel Jan 24 '13 at 3:15

I guess if each of those keys had an explanation with it, we'd just end up with the manual again... –  Jake Jan 24 '13 at 8:21

@Jake, it could be a short explanation, only as a reminder and not a complete reference. Also, these keys could be separated in two lists, one for frequented used and other for rarely used, in order to facilitate looku ps. –  JLDiaz Jan 24 '13 at 8:54

I love automated approaches :-) Instead of a short manual explanation, we maybe could automatically add the respective chapter heading and pgfmanual page number (maybe from the aux file) as a reference to each item. –  Daniel Jan 24 '13 at 10:05

@TimParenti There is an index at the end of the manual. Keys are also marked. –  percusse Jan 24 '13 at 20:06
