Hello Salman, (second attempt for this mail...)
\startitemize[..,..,..][..,..=..,..] ... \stopitemize
1) The \startitemize is optionally followed by a comma separated list of parameters enclosed in brackets.
right.
2) Then a set of key-value pairs enclosed in brackets follows. Again this is optional.
correct.
If this is correct, then what about \setupitemize?. It says
\setupitemize[.1.][..,.2.,..][..,..=..,..]
So again let me guess .1. stands for a number
no, not really. "1" stands for "look at description 1, so it can be a number or the keyword "each"
The third set could be key-value pairs
right
What about the set in the middle?
Same as the first one in startitemize. It says ".2." : look at number two which is the "standard, n*broad, n*serried ..." Look at the first link I have in my signature and look for \setupitemgroup and \startitemgroup. (See also the comment in \setupitemgroup. The description is slightly different from the on in the beginners manual) Patrick -- texshow-web: http://members.ping.de:8061 ConTeXt wiki: http://members.ping.de:8062
