Nexus offers a number of emotions(also called emotes) for players to use to express themselves. To have your character do an emotion simply press : (that is hold shift and press ;) and then a letter (from letters a-p).
Here is a listing of each emotion you can do:
- A Laughter
- B Grief
- C Shame
- D Affection
- E Boredom
- F Sleepiness
- G Suprise
- H Anger
- I Sarcasm
- J Shrug
- K Annoyed
- L Dance
- M Bow
- N Triumph
- O Downcast
- P Kiss
Side note: When you read a board or mail, your character automatically does the :E Boredom emote. Also when you are idle for an amount of time, your character automatically does the :F Sleepiness emote.
