//
// This is a Greasemonkey user script.
//
// To install, you need Greasemonkey: http://greasemonkey.mozdev.org/
// Then restart Firefox and revisit this script.
// Under Tools, there will be a new menu item to "Install User Script".
// Accept the default configuration and install.
//
// To uninstall, go to Tools/Manage User Scripts,
// select "GMail Mark Read Button", and click Uninstall.
//
// Based on the Gmail Delete Button script by Anthony Lieuallen and the
// Gmail Smart Delete script by Paul Moriak. I'm learning both gmail
// hacking and Javascript, so this is probably horrible...
//
// Incorporated fixes from Tom Spear's version (http://userscripts.org/scripts/show/6237).
//
// Requires Greasemonkey 0.6.4 and Firefox 1.5 or later.
// Works with Firefox 2.0.
//
// ----------------------------------------------------------------------------
// WHAT IT DOES:
// If any unread message is selected it places a "Mark Read" button on the page
// next to the Archive button. If read messages are selected the button
// changes to "Mark Unread".
// ----------------------------------------------------------------------------
// HISTORY:
// 2005-04-25 0.1 Initial version.
// 2005-05-03 0.2 Button works in Spam folder also.
// 2005-05-18 0.3 Now works with Greasemonkey 0.3.3.
// 2005-05-18 0.4 Rewrite. Button is now only enabled if unread messages are
// selected.
// 2005-05-26 0.5 Updated from Paul Moriaks latest version of Gmail Smart Delete,
// to add support for keyboard shortcuts.
// 2005-05-27 0.6 Fix a problem interoperating with the Smart Delete button.
// This script was disabling the Delete button when reading a
// mail item. Also, the Mark Read button now does not appear
// at all in a mail item.
// 2005-05-27 0.7 Small changes to comments.
// 2005-07-25 0.8 Fix for changed gmail URLs.
// 2005-11-22 0.9 Fixes for GM 0.6.3 and FF 1.5. Removed keypress stuff.
// Added code to toggle between mark as read and mark as unread.
// 2006-04-20 0.10 Fixes for recent Gmail DOM changes. Works with FF 1.5.0.2.
// 2006-11-07 0.10b Fixes for wrapping of displayed items
// 2006-11-07 0.10c Fixes for the previous fixes where I forgot the bottom control bar
// 2006-11-08 0.10d Fixes for all wrapping issues, achieved by shrinking the font size
// for the displayed items.
// 2008-02-14 1.0 Merged Tom Spear's fixes. Added global debug variable.
