Controls on the toolbar:
Bold/Italics, Link, Mention, Icon switch to wikitext:
Bold/Italics icon pops up a menu:
Mentions icon pops up as an inspector modal, similar to the VE link modal. It should have an arrow pointing at the cursor.
The mentions box is pre-populated with usernames that have already posted in this topic. The names should be in alphabetical order. Don't include IP addresses for anons.
(What happens when it's too many? Scroll bar? When does that happen? What does it look like with no names?)
Switch to wikitext: T90763: S6. Flow: Switching from VE to wikitext and back without losing content VE icons disappear, and the icon switches to reverse colors.
Text at the bottom says: "Wikitext uses markup, and you can preview the result any time."
"Preview the result" is a link -- clicking on it switches the user back into VE mode.
"Markup" is not a link.
Tooltips: Hovering on the wikitext icon pops up a tooltip.
In VE: "View message as wikitext"
In Wikitext: "View message as rich text"
We also decided to put a ... menu to the right of the main 3. Behind that will be keyboard shortcuts.
