As far as I can tell, ConTeXt doesn't include a keycaps font. I recently
created my own and would like to share it with anyone else that might
find it useful. I've included a sample document with it. If you're on a
*nix system with a working copy of ConTeXt and make, just type "make" to
build it.

I'm not sure what it would take, but I think this can be include with a
future version of ConTeXt if you're interested, Hans.

Very nice!  I would like them to lay closer to a standard baseline,

I'm not sure what you mean by "lay closer to a standard baseline". The
baseline of the glyph inside the key is aligned with text outside the
key. I waffled back and forth trying to find the most attractive
position while building the font. The majority of keycaps fonts I looked
at chose the same baseline.

I welcome any tweaking. Especially the addition of keys from other
keyboard layouts.

Ah, of course.  That's perhaps as good as it gets,

It occurs to me that one thing that would be particularly useful in a 
keycaps font would be pieces from which one could construct a "key" around 
a letter from another font -- specifically, a left side, a right side, and 
a middle portion made up only of purely horizontal lines so as to be 
extensible.  One could potentially also have these in "short" and "tall" 
versions, depending on how the rest of the font worked.

Having looked at the uploaded .pdf, I agree: very nice!

I do agree with Nikolai that there appears at first glance to be a bit of a 
baseline problem.  As you mention, though, the baselines are "right".  The 
actual difficulty, in my opinion, is that the font is just a bit too small, 
and so the _tops_ of the keys are too low -- it looks odd for them to be 
lower than the tops of the capital letters, when the depth of the keys is 
so large.

Here's what I would suggest for the enlargement amounts: consider the 
examples where you have a key enclosed in parentheses.  The bottom of the 
key drops below the bottom of the parentheses just a bit, which in my 
opinion looks quite good.  I think it would be good to enlarge the font so 
that the top of the keys extend above the tops of the parentheses by an 
equal amount, so that this would look balanced -- in other words, so that 
the vertical center of the keys is aligned with the "math 
axis".  (Admittedly, this does mean realigning the baselines, rather than 
just scaling the font.)

This enlargement would also hopefully enable you to make the text within 
the keys larger -- at present, they're just barely legible on my 
1280-pixel-wide monitor when I have the sample sheet sized to 
full-secreen-width.

Aside from that quibble, though, they do look quite good.

Why not just center the characters? No problem for most of them since 
they have the same height (due to the upppercase char); All keyboards 
are different in positioning, so it does not hurt that much. By 
centering on gets a better look and feel.

Concerning the 'construct a key' approach, how about the following:

- provide shapes for a single, double-wide, tripple-wide, tripple 
height, enter-shape keys.
- next we can make a series of virtual fonts using the new condensed 
latin modern (sans or monospaced)

that way also keyboards for other languages can be constructed; I guess 
that a simple perl/ruby script can construct the virtual font.

Nice initiative

Hans

 Wouldn't it be reasonable to just create these borders via MetaFun?
That way, I can have \key{\triangleleft home}, \key{any}, or even
special keys for play station etc., without them being provided originally.

 Oh, and I could have keyboard keys matching my current font, whatever
that may be.

that would be true if there was a keycaps shapes font that could be combined with a regular font (making a virtual one)

(we can ship a few font if needed; context also comes with two navigation fonts)

I have uploaded a new version of the font with the baseline shifted.
Specifically, I have aligned the top of the heavy black bottom bar with
the baseline. In my documents at least, this is much more attractive.
Not sure how I arrived at a different conclusion initially.

http://blogs.gurulabs.com/stuart/

As suggested by Hans, I've also been trying to understand more about
defining custom encodings. Perhaps I will soon be able to post a version
of the font with easier to access characters.

is that really texnansi? these Function-1 keys etc are not in texnansi ... 

so, an option is to make a special encoding vector, say keycaps.enc and 
define proper names, like 

\definecharacter functioni   ..
\definecharacter functionii  ..
\definecharacter functioniii ..
\definecharacter functioniv  ..

which permits: 

\definefont[keycaps][...][encoding=keycaps]

{\keycaps ABC\functionvii DEF}

\begin{cases} .. \end{cases} in ConTeXt

Hi,

I have tried with:

\startcases
.. 
\stopcases

and many others variations but I have got only errors.
Any hint?

Thanks.

Much like the bmatrix environment, the cases environment is an AMSmath 
package feature, and ConTeXt at present has very few of the direct 
equivalents to those implemented.  You'll need to make this one up with a 
Plain TeX \matrix, as well.  (The TeXbook is a pretty good reference for this.)

Something like this should work, to recreate the example from page 8 of the 
AMSmath manual:

   P_{r-j} =
   \left\lbrace
     \matrix{
        0                 \hfill& \text{if $r-j$ is odd}   \hfill\cr
        r!(-1)^{(r-j)/2}  \hfill& \text{if $r-j$ is even}  \hfill\cr
     }
   \right.

The \left\lbrace and \right. create the properly expanded brace at the 
left, the \matrix handles putting things in the right places, the \hfills 
make each of the columns left-aligned, and the \text{} commands (which _do_ 
exist in ConTeXt, unlike in Plain TeX) typeset their arguments as text 
rather than math.

I should follow my own advice!  As the TeXbook points out, Plain TeX has a 
perfectly good \cases command which is also present in ConTeXt, and which 
you use like this:

   P_{r-j} =
   \cases{
        0                 & if $r-j$ is odd,\cr
        r!(-1)^{(r-j)/2}  & if $r-j$ is even.\cr
     }

Note that, in this version, the text in the second column is _not_ enclosed 
in a \text command; the \cases command handles that automatically.

In any case, the output is identical to the previous version I gave you, 
but this is easier to type.

All I know for sure is that it Works For Me(tm). Unfortunately, my

That would be easier to use. It's also worth noting that I saw some, but
not all, keys defined in Unicode.
