i believe he wants [ and ] to map to [ and ] so he doesn't have to remember that they are [ for [ and ] for ]

i just keep a link to handy character table in my bookmarks.

if you use <code> tags in your non code paragraphs so you can type [ and ] then when people d/l your code they have a bunch of stray [ and ] characters in the most inapropriate places.

try and download this:

print "hello$/";
