Do you get sick of typing \verb.\gamma., \verb.\ref{myref}., and 
\verb.\frac{x^{2}}{3}.?

I have set up a special keyboard for typing \LaTeX\ commands in
the Alpha editor.  The keyboard speeds up typing
of many common \LaTeX\ commands.  It is especially useful when typing
equations, which many of us seem to do quite a bit.  This keyboard is 
based on a keyboard layout that I originally designed for use on an 
Apollo workstation, then modified for use with Alpha 4.03.  The current 
version is intended for Alpha 5.0 (but comes with no warranty!).

When enabled (see {\sf Latex Keys Help} in the {\sf Help} menu), the 
\LaTeX\ keyboard is automatically activated (i.e., the 
editor switches to \TeX\  mode) when you  
edit a file whose name ends in \verb'.tex'.  
If your file doesn't yet end in \verb'.tex' or 
if the editor is thrown out of \TeX\ mode for any reason, you can 
reactivate \TeX\ mode by selecting {\sf 
Set Tex Mode} from the {\sf Misc} menu. 

All (except one) of the key combinations in the \LaTeX\ keyboard use 
the {\sf Option} 
key, often in combination with the {\sf Shift}, {\sf Command} and 
{\sf Control} keys.
(Do not confuse the {\sf Command} and {\sf Control} keys.  The 
{\sf Command} key has the ``flower'' symbol on it.)
To get a $\phi $ in your file, press {\sf Option \verb.f.}, and 
``\verb.\phi .''
will appear at the cursor.  An uppercase phi ($\Phi $) is obtained by 
{\sf Option Shift \verb.f.}.
Select {\sf Latex Keys Help} in the {\sf Help} menu to get a 
listing of all the characters and functions.

The ``key'' feature of this keyboard is the tabbed functions.  For instance,
to get the fraction three-fifths, you usually have to type
\verb.\frac{3}{5}. (i.e., \verb.\., \verb.f., \verb.r., \verb.a., \verb.c., 
\verb.{., \verb.3., \verb.}., \verb.{., \verb.5., \verb.}.---11 keys in all) 
which isn't much fun.  
The \LaTeX\ keyboard has tabbed 
functions, so, instead of the above, you would type {\sf Option \verb./.},
\verb.3., {\sf Tab}, \verb.5., {\sf Tab}, (five keys)
and you've got your fraction.  Now you can type fractions, integrals, 
overbars, etc. without ever using those \verb.\{}. characters.  Also, you can
nest these functions as deep as you like.  As you'll soon see, 
this is done by putting $\bullet$ marks into the function, which the 
{\sf Tab} key
searches for.  For example, the fraction key sequence {\sf Option \verb./.}
 types ``\verb.\frac{}{.$\bullet$\verb.}.$\bullet$'' 
and puts the cursor inside the first set of braces; hitting the {\sf Tab} 
key moves
the cursor to the next $\bullet$ (and erases the $\bullet$).  
All the other functions are similar.
The are also F-keys which produce a tabbed \verb.equation. or 
\verb.eqnarray. environment.

The special key combinations are listed in the following tables.  Note 
that there are no special keys for Greek letters which are identical to 
Roman letters (e.g., A, B, P).  

I hope you find this layout useful.  If you make any improvements, please 
pass them along to me.
