VS Code end snippet by copying text or selecting text

I would like to modify my VS Code snippet so that after it completes, I have either copied a piece of the text output, or have that text selected.

I have the following snippet currently:

    "new section heading with link": {
        "prefix": "iheading",
        "body": [
            "$1## ${CLIPBOARD}",
            "",
            "This section: [${2:${CLIPBOARD}}](${TM_FILENAME}#${CLIPBOARD/(([\\w-]*)([^\\w\\s]*)*(\\s)*)/${2:/downcase}${4:+-}/g}) | [Back to top](#top)"
        ],
        "description": "Insert heading and link to section whose heading text is in the clipboard"
    }

I use this in markdown files. Let's say I have copied the text "Howdy" and am editing a document called "notes.md". After running the snippet, the output will be:

## Howdy

This section: [Howdy](notes.md#howdy) | [Back to top](#top)

What I would like is to end that snippet with the text [Howdy](notes.md#howdy) either copied to the clipboard, or selected - so that my next action can be to copy it.

Final snippet after advice from @Mark

"new section heading with link": {
    "prefix": "iheading",
    "body": [
        "## ${CLIPBOARD}",
        "",
        "This section: ${1:[${CLIPBOARD}](${TM_FILENAME}#${CLIPBOARD/(([\\w-]*)([^\\w\\s]*)*(\\s)*)/${2:/downcase}${4:+-}/g})} | [Back to top](#top)"
    ],
    "description": "Insert heading and link to section whose heading text is in the clipboard"
}

You could wrap that output you want to be ultimately selected with ${3:...} like so:

"This section: ${3:[${2:${TM_SELECTED_TEXT}}](${TM_FILENAME}#${TM_SELECTED_TEXT/(([\\w-]*)([^\\w\\s]*)*(\\s)*)/${2:/downcase}${4:+-}/g})}"

After triggering the snippet you will have to tab twice to get to that third tabstop - your text will now be selected - and Ctrl+C to copy it.

Wrapping some output in a tabstop like ${3:...} will select it.

If you didn't need those tabstops 1 and 2, you could automate the copying by creating a "macro-like" keybinding. First, modify your snippet to:

"new section heading with link - from selected text": {
  "prefix": "iheading from selected text",
  "body": [
    "## ${TM_SELECTED_TEXT}",
    "",
    "This section: ${1:[${TM_SELECTED_TEXT}](${TM_FILENAME}#${TM_SELECTED_TEXT/(([\\w-]*)([^\\w\\s]*)*(\\s)*)/${2:/downcase}${4:+-}/g})}"
  ],
  "description": "Insert heading and link to section whose heading text is in the clipboard. Linked to keyboard shortcut"
}

where I removed your tabstops 1 and 2. Then create a keybinding that will insert the snippet and then copy the selected new tabstop 1 text:

// in your keybindings.json

{
  "key": "ctrl+shift+/",        // whatever keybinding you want
  "command": "runCommands",
  "args": {
    "commands": [
      {
        "command": "editor.action.insertSnippet",
        "args": {
          "name": "new section heading with link - from selected text"
        }
      },
      "editor.action.clipboardCopyAction"
    ]
  },
  "when": "editorHasSelection && editorTextFocus && !editorReadonly && editorLangId == markdown"
}

Run that keybinding on your selected text and voila your desired text has been copied to the clipboard.
