Reviewer guidance

Suggested review: Light-touch code review, then manual QA.

• User-visible files changed: contentcuration/contentcuration/frontend/shared/views/TipTapEditor/TipTapEditor/extensions/SmallTextExtension.js.
• In a full exercise editor, check that Ctrl/Cmd+Shift+S strikes the selection through without changing the block, in Chrome and Firefox on Windows and on macOS.
• In Firefox, check that the shortcut doesn't also open Firefox's own Ctrl+Shift+S screenshot tool.
• Inside a code block the editor now leaves the key to the browser, so check that the browser's default action is acceptable there.

• Small text now has no keyboard shortcut; should it get a different one, or is the format dropdown enough?

QA team: in the exercise editor, Ctrl+Shift+S (Cmd+Shift+S on Mac) now applies strikethrough. Before, it changed the line to Small text. Regressions are most probable in Small, heading and list lines, and in answers and hints.

Sign in as a channel editor. Add a new exercise and open its Questions tab.

1. Strike question text
   1. Click New question. Type text in the Question editor and select it.
   2. Press Ctrl+Shift+S. The text is struck through and the format dropdown shows Normal.
   3. Press Ctrl+Shift+S again. The strikethrough goes away.
   4. Strike the text again and reload the page. The strikethrough stays.
2. Small, heading and list lines
   1. Choose Small from the format dropdown for a line.
   2. Strike one word in it with Ctrl+Shift+S. Only that word is struck through. The line stays Small.
   3. Do the same in a Header 2 line and a Bullet list item. The line type does not change.
   4. Press Ctrl+Z. Undo removes only the strikethrough.
3. Answers and hints
   1. Make the question Multiple Choice and add a hint.
   2. Strike a word in an answer option and in the hint. Each word is struck through. No line becomes Small.
   3. Reload the page. Both strikethroughs stay.

Look out for:

• On a Mac, press Cmd+Shift+S in the Question editor. Look out for a result different from Ctrl+Shift+S.
