LaTex notes and Gnome shortcuts

As you all know:

LaTeX is a high-quality typesetting system; it includes features designed for the production of technical and scientific documentation. LaTeX is the de facto standard for the communication and publication of scientific documents. source

LaTex, although very powerful, requires some time to be understood. In my exeprience, the easiest way to get acquainted with it, it is to copy from existing documents the code that produces the desired result. The file attached to this document contains some sample documents that I use as models.

Add a custom keyboard shortcut to Gnome
In order to add a keyboard shortcut for a command, in Gnome, do the following:

1. In a shell, run:

% gconf-editor

2. Go to

apps > metacity > keybinding_commands

and set the first free command with the string corresponding to the program you want to run.
Example: I set the command_1 to /etc/acpi/screenblank.sh, the command that turns off the screen.

3. Under

apps > metacity > global_keybindings

set the run value corresponding to the command defined in the previous step to the desired keyboard combination.
Example: I had to set the field run_command_1 to F3.
