Chatten
Overview
Chat
You can create a chat with someone using the Plus icon > New direct message. There you can find a person using the Matrix ID (e.g.: @name:uni-wuppertal.de) or the name (first name last name). Alternatively, you can also enter an email address, then a chat invitation will be sent to this person (you can only chat if this person has a Matrix account).
The following is good to know:
- To make a line break on the PC, press Shift + Enter (and Enter sends the message).
- Files (including images) can be sent up to a size of 25MB.
- Emojis can be reached by starting with a colon “:” and typing at least two more letters. If you don’t know the emoji name you want by, you can scroll through many emojis by clicking on the smiley symbol on the right in the input line.
- There is a search to find text in chat, but encrypted messages cannot be searched via the web application. However, you can search via the desktop client. This is because Element has no access to the messages (the encryption means that no one can read the messages, not even Element).
- Der Chat-Verlauf (von Direktnachrichten und Räumen) kann exportiert werden (HTML, Klartext, JSON).
Markdown
Messages can also be formatted in Matrix Element using text formatted in the markup language MarkDown. Here are some examples:
| Result | to type |
|---|---|
| Fat | **Fat** |
| Italic | Italic |
| | Quote | > Quote |
| Headline 1 | # Headline 1 |
| Headline 2 | ## Headline 2 |
| Matrix help | [Matrix help](https://element.uni-wuppertal.de/docs/) |
|
 |
| List entries | * List entry* List entry* List entry |
| Numbered lists | 1. Numbered list 2. Numbered list3. Numbered list |
|
$\displaystyle\sum_{j=0}^m\sum_{i=0}^n\\j\ne i$ |
The current MarkDown specification can be found here..
LaTeX formulas are not visible in the chat by default. To do this, you have to go to All Settings > Lab and under Communication you can activate LaTeX math formulas. This is a so-called lab function.
Room
You create a new room (or group chat) using the Plus icon > New room. You also have to decide whether you want to send encrypted messages. You can always activate encryption later, but once it is activated, you cannot undo it. You can also use the Plus icon to go to Explore public rooms to find and join rooms.
When the last person in the room leaves, the room can still be found in the archive for about 7 days, but is then permanently deleted. So if an administrator wants to delete the room, he should first “kick” everyone and then leave to initiate the later deletion.
Under the room information there is the option Copy link, which gives you a link to share the room. Alternatively, the room can also be shared using the room address.
Room address
A room address can be created for a room. It has the following structure: #Roomname:uni-wuppertal.de. This address makes it easier to find the room or you can enter this address in the chat to link to the chat.
Global vs Local: There are local and global room addresses. Local addresses are only visible on the Matrix home server, i.e. at the University of Wuppertal. Global addresses
are visible on all Matrix servers (by everyone who uses Matrix).
Creation: To make an address global you first have to create a local address. The room address must not contain any spaces.
Authorization level
There are three roles: standard, moderator and administrator (and custom roles). You can set how much permissions they should have, e.g. whether they can write messages, invite others and so on.
Room access options
The Space Members access option means that the room is public, but you must join the room to be able to read it.
Notifications
General settings
Which notifications should trigger sounds and how loud they should be can be set via Settings > Notifications.
Chat specific settings
In addition, each chat and room has settings for notifications. You can access them by right-clicking on the chat or room and then selecting Settings > Notifications.
