I am able to create keybinding for code span (markdown.extension.editing.toggleCodeSpan) which surrounds the text with backticks.
Is it possible to setup keybinding for code block (triple backticks or 4-space indent)?
You can add
{
"key": "your keybinding",
"command": "editor.action.insertSnippet",
"args": {
"snippet": "```\n$0\n```"
},
"when": "editorTextFocus && editorLangId == markdown"
}
to your keybindings.json which can be opened here

Thanks, looks powerful. I enhanced it a bit to include the selected text, when shortcut is pressed on a selection.
{
"key": "ctrl+shift+C",
"command": "editor.action.insertSnippet",
"args": {
"snippet": "```\n${TM_SELECTED_TEXT}$0\n```"
},
"when": "editorTextFocus && editorLangId == markdown"
}
