@servicedesk please create an implementation plan based on the above, including suggested code changes

@zaakiy Implementation plan for the lightweight Copy action:

Approach

Add a full-body Copy control in the shared comment viewer (CommentPanel), next to Quote. Issue/PR descriptions and comments all render through that panel, so one change covers the stated scope without touching each caller separately.

Existing callers that get Copy automatically:

• Issue description — IssuePrimaryPanel
• Issue comments — IssueCommentPanel
• PR description — PullRequestDetailPage
• PR comments — PullRequestCommentPanel

This reuses CopyToClipboardLink / ClipboardJS (same pattern as AI chat “Copy as Markdown”). Markdown is already available when the viewer is built (getComment(), same source Quote uses), so click does not need a new server round-trip or HTML→Markdown conversion.

Suggested code changes

1. CommentPanel.html (viewFrag action row)
   Insert a Copy control beside Quote, matching the existing text-link style (Edit / Quote / Delete), e.g. after Quote and before Delete:

   <wicket:enclosure child="copy">
     <span class="d-first-child-none dot mr-2"></span>
     <a wicket:id="copy" class="text-muted text-hover-primary mr-2"><wicket:t>Copy</wicket:t></a>
   </wicket:enclosure>
   

   Text label (not icon-only) keeps the row consistent; tippy can still show copy/copied feedback.

2. CommentPanel.java (newViewer())
   Add a CopyToClipboardLink with an IModel that returns getComment(), e.g. tooltip _T("Copy Markdown") / default “Copied to clipboard”.
   Visibility: show when content is non-blank (StringUtils.isNotBlank(getComment())). Unlike Quote, do not require a signed-in user — copy only needs view access.
   Optional: isCopyEnabled() defaulting to true if a caller ever needs to hide it (mirrors isQuoteEnabled()).

3. No new JS / libraries
   copy-to-clipboard.js already supports links without an SVG (icon swap is skipped; tippy still updates). Do not add selection mapping or reverse Markdown conversion.

4. Translations
   Use <wicket:t>Copy</wicket:t> and _T(...) for the tooltip. Do not hand-edit generated Translation_*.java files.

5. Out of scope for this change

   • Code review comments (CodeCommentPanel has its own Quote row; can be a follow-up if desired)
   • Selection-aware copy
   • Any extra Ajax on click

Why this stays lightweight

• Server: no new endpoint or compute on click; text is taken from the already-loaded entity field at render.
• Client: one extra anchor + existing ClipboardJS helper; no new dependency.
• Scope: full body only, same data Quote already uses.

Manual test plan

• Issue with description: Copy puts full Markdown on clipboard; empty description hides Copy.
• Issue comment: same; works when logged out if the comment is visible.
• PR description and PR comment: same.
• After Edit/Save, Copy reflects the updated Markdown.
• Quote / Edit / Delete behavior unchanged.

Does this plan look good to proceed?

LGTM

@zaakiy Thanks for the LGTM. I do not have permission to write code in this project (tod issue checkout --for-write returned HTTP 403), so I cannot implement the Copy action myself. @robin please take over implementation based on the approved plan.

Implemented the approved plan: added a Copy control next to Quote in CommentPanel, reusing CopyToClipboardLink with the already-loaded Markdown. It covers issue/PR descriptions and comments, is shown when content is non-blank (no login required), and can be hidden via isCopyEnabled().
