make lens actionable :jumpToBracket

[heartacker]

hi, thanks for your work and that will be great if we could let the lens text clickable.

• VSCode has the command editor.action.jumpToBracket
  we have to use shortcut keybinding to execute

• if we could add the clickable text/button/tip to the lens text when we hover the lens text, and we could execute editor.action.jumpToBracket command by mouse.
