# Composer Features
## Auto Complete
- Hitting tab tries to auto-complete the word before the caret as a room member
- If no matching name is found, a visual bell is shown
- @ + a letter opens auto complete for members starting with the given letter
- When inserting a user pill at the start in the composer, a colon and space is appended to the pill
- When inserting a user pill anywhere else in composer, only a space is appended to the pill
- # + a letter opens auto complete for rooms starting with the given letter
- : open auto complete for emoji
- Pressing arrow-up/arrow-down while the autocomplete is open navigates between auto complete options
- Pressing tab while the autocomplete is open goes to the next autocomplete option,
wrapping around at the end after reverting to the typed text first.
## Formatting
- When selecting text, a formatting bar appears above the selection.
- The formatting bar allows to format the selected test as:
bold, italic, strikethrough, a block quote, and a code block (inline if no linebreak is selected).
- Formatting is applied as markdown syntax.
- Hitting ctrl/cmd+B also marks the selected text as bold
- Hitting ctrl/cmd+I also marks the selected text as italic
- Hitting ctrl/cmd+> also marks the selected text as a blockquote
## Misc
- When hitting the arrow-up button while having the caret at the start in the composer,
the last message sent by the syncing user is edited.
- Clicking a display name on an event in the timeline inserts a user pill into the composer
- Emoticons (like :-), >:-), :-/, ...) are replaced by emojis while typing if the relevant setting is enabled
- Typing in the composer sends typing notifications in the room
- Pressing ctrl/mod+z and ctrl/mod+y undoes/redoes modifications
- Pressing shift+enter inserts a line break
- Pressing enter sends the message.
- Choosing "Quote" in the context menu of an event inserts a quote of the event body in the composer.
- Choosing "Reply" in the context menu of an event shows a preview above the composer to reply to.
- Pressing alt+arrow up/arrow down navigates in previously sent messages, putting them in the composer.
