I found imenu very useful. Especially when it driven by keyboard instead of
mouse:

  (defun my-popup-menu ()
    "Menu from keyboard by emulating mouse event."
    (interactive)
    (mouse-popup-menubar
     (list (list (/ (display-pixel-width) 2) 10) (get-buffer-window (buffer-name)))
     nil)
    )
  (global-set-key [f10] 'my-popup-menu)
  (global-set-key [apps] 'my-popup-menu)
  (global-set-key [menu] 'my-popup-menu)

  (require 'imenu)

  (defun my-imenu-to-menubar ()
    "Force imenu building when (menu-bar-mode -1)."
    (when imenu-generic-expression
      (imenu-add-menubar-index)
      (run-hooks 'menu-bar-update-hook) ))
  (mapc (lambda (hook) (add-hook hook 'my-imenu-to-menubar))
        my-devel-mode-hook-list)

I think this is useless as bash (and sh) allow local variables.

It will be useful to teach 'semantic-ia-*-jump' jump to definition.

Also modular bash scripts include common parts so definition may come from
another files...

For variable I can suggest to use 'occur' or 'lgrep/rgrep':

  (defun my-sh-var-occur ()
    (interactive)
    (let ( (name (thing-at-point 'symbol)) )
      (when name
        (occur (concat name "="))) ))
