All settings (highlight color and phrases, default away message and scrollback buffer) accessed from your account menu

/away/

Usage: /away [optional away message]

Like other chat programs, /away will mark you away and respond to missed PMs automagically.

/tag

Usage: /tag [playername] or right click their name in chat and choose tag from right-click menu

Player's name will be highlit until you exit chat or choose tag them again. Useful for keeping track of conversations in busy channels

Tab Nick-Complete

Type the first character or first few characters of a players name and hit tab to expand to the first found player's name. Hit tab again to expand to the next found character, alphabetically. If the script detects that you're writing a PM to the player, spaces in their name will be replaced with underscores automagically.
Caveats (read before submitting bug reports)

• KOL Chat Limitations:
  • Because there are no join/exit messages:
    • the list of player names that can be tab completed will be limited to those players who have said something in a channel, players who you've PMed or whois-ed, players that have PMed you, and any players listed as a result of a /who, /who <chan>, or /friends.
    • Players will not be removed from this list if they leave chat.
  • Players with spaces in their names are slightly problematic:
    (Example: typing 'a' then tab will find 'a player', but typing 'a player' then tab will find 'player5014' instead).
• Firefox Limitation:
  • Changing the contents of the graf form will result in the text field being scrolled to the left, hiding overflow text though your selection/insertion point won't change. Use the left/right arrow keys to see what you were just typing if this happens. There appears to be no way to solve this problem currently, without converting the script to a full blown extension to gain access to privileged code.

Phrase Highlighting

Add words/phrases to a highlight list (your player name, items you're trading for, etc.) to be highlit when they're said chat or PM. Supports regular expressions as well.

• 'Quote' post function
• (optional) a quick-reply section
• (optional) setting to hide custom avatars in clan threads
