The new lesson experience gives you two ways to insert anything that isn't plain text. Both pull from the same catalogue of blocks.
The slash menu
Type / on an empty line. A menu opens with every block grouped by type.
Keep typing to filter. /mc jumps to Multiple Choice. /yt finds YouTube. /call brings up the Callout group.
Arrow keys move through the list, Enter inserts the highlighted option, Escape closes the menu.
The slash menu is the fastest way to work if your hands are already on the keyboard.
The plus menu
Hover over the left margin of any block and a + button appears. Click it to open the same menu in a clickable form, with previews for each block type.
Same options as the slash menu. Use this one when you'd rather scan than type.
What you can insert
Text formatting: headings (H1 to H4), divider, code block, page break
Media: image, YouTube video, table
Questions: Multiple Choice, Select All Correct, True / False, Match, Resequence, Free Response, Long Answer, Reflection
