Defining and Editing Shortcuts in Mathematica

I always wanted to edit my own keyboard shortcuts in Mathematica to do such repetitive tasks as inserting page breaks, selecting the current cell you're working in, applying styles (such as DisplayFormula that doesn't have an alt-# shortcut), etc.  I stumbled upon two interesting files in C:\Program Files\Wolfram Research\Mathematica\6.0\SystemFiles\FrontEnd\TextResources\Windows called KeyEventTranslation.tr and MenuSetup.tr.  These files contain a large number (if not all) of where the shortcuts are coded into the program.  However, I don't know how to edit these properly!  Any slightest change will cause Mathematica not to load properly.  How would I go about:

(1) Defining a shortcut to select right away the cell that I am working in?
(2) Adding a page break shortcut?
(3) Editing style formatting shortcuts?

Thanks,
Julian

I've found the solution after a long time spent mucking around the keyeventtranslation.tr and menusetup.tr files... to anyone still searching for an answer out there check http://www.mathematica-users.org/webMathematica/wiki/wiki.jsp?pageName=Main_Page

lookup anything about keyboard shortcuts and you'll get an idea of what to do (its as simple as splicing in MenuKey["character",Modifiers->{whatever you want}] after the command that you want).  Be careful about syntax though, as one character out of place will cause Mathematica to crash!

Attached are my modified KeyEventTranslation.tr and MenuSetup.tr files (change extensions from txt to tr).  My mods in keyeventtranslation are obvious, but in menusetup check PageBreak, and the Table/Matrix commands.

It may be possible, but I don't think you can just edit those files. I suspect that Mathematica checks the integrity of the files before it uses them.  There are already shortcuts for style formatting. I suspect that there is already one that will do the selection you want (but I am not sure what it is so I don't know for sure). I don't see one for inserting a page break though. Have you looked here:

yes absolutely
I checked all the existing shortcuts, but I want to create/customize my own.... I've heard its possible if you edit the files properly.

Okay, assuming that it can be done (and looking around, it appears that you are right, it can), I suggest that you start small. Pick one function and remap it to a different key. If that works, then try adding a new mapping in KeyEventTranslations.tr. Just work your way up to what you want.
