Odd number of new Players seem to accidentally Toggle highlighting

(playing ruthless where global chat is quite small and i rarely have global chat active.)

in the last 10 days i noticed 4 new players so far, who asked how they can do the quest with the necropolis gravekeeper. turned out all 4 times they somehow managed to toggle highlighting and thus werent even able to see drops/interactables.

having Z as key-default for this toggle is weird because some keyboard layouts have Z right under A. i can imagine that some players are much more prone to hit that key by accident. can not explain this otherwise.

just thought this is worth mentioning.
