Here is a two triggs for zMud that will color the \"|\" before the skill/spell
and the cost of the skill/spell as red or green according if you can
train/study em.
Maybe not precicely what you were looking but helps my life when i got three
guilds to train. Simply copy&paste to zMud\'s command line and hit enter. It
will update itself everytime you check your score (i got exp indicator in
Short Score so i get it updated bit frequently).
#REGEX \"grep Player level and Experience\" {^Player level:
(\\d+)\\s+Experience: (\\d+)$} {#Variable (Player_level) {%1};#Variable
(Experience.Current) {%2}} \"Character\" {case|notrig}
#REGEX \"Color skills/spells available for training/study\" {^(\\|)
(.*)\\s+\\|\\s+\\d+ \\|\\s+\\d+ \\|\\s+\\d+ \\|\\s+(.*) \\|} {#If (0 < %3 & %3
< @Experience.Current) {#PCOL green %x1;#PCOL green %x3} {#PCOL red %x1;#PCOL
red %x3}} \"Coloring\" {case|notrig}
A
