			Additional spaces are placed into the equation by using the \ without a trailing character. Escape characters, of which there are a few in Moodle's TeX Notation, have the \ in front of them. These are usually set aside for reserved characters.

	Using TeX in Windows is simpler than it used to be. Download and install a TeX for Windows program, like [http://www.miktex.org/ MikTeX]. (MikTeX is probably the most useful at this point in time for Windows Users.) Also, a graphics package is required for rendering the scripted TeX statements into images, and probably the most readily available and easily installable program useful for this purpose would be [http://www.imagemagick.org/script/index.php ImageMagick]. While there may be better programs available for these purposes, these are the most immediately useful. ~~They~~ are easily installed and configured.

	The discussion in these pages is centred entirely upon using the TeX Notation filter in Moodle. The code examples given are proven to work inside Moodle, but much of the discussion that addresses Tex syntax can be generalized to other applications that parse Tex~~. Moodle Docs use a different, more general, TeX rendering scheme than does Moodle~~. So far, all items tested work in both Moodle 1.9.x and Moodle 2.0 without change or further refinement.
