How to automatically press the Tab key to execute minibuffer-complete after executing imenu?

Question

I first set up this key binding : (global-set-key (kbd "<f4>") (lambda () (interactive) (other-window -1)))

When I use imenu I always have to perform the following steps:

Step 1: Press M-x
Step 2: type imenu , Press RET
Step 3: Press TAB ;; run minibuffer-complete
Step 4: Press f4 ;; run (other-window -1) for switch to *Completions* buffer
Step 5: Press C-s ;; run isearch-forward

I want to use a function to perform the above 5 steps.

Is this possible? This is useful when there are a lot of functions.

Similarly, if want to display struct, need to insert between the second and third steps:
Step 3: type Class , Press RET

My current solution is to use xdotool:

show struct list: (global-set-key (kbd "<f8>") (lambda () (interactive) (shell-command "xdotool key alt+x && xdotool type 'imenu' && xdotool key Return && xdotool type 'Class' && xdotool key Return && xdotool key Tab && xdotool key F4 && xdotool key ctrl+s")))

show function list: (global-set-key (kbd "<f9>") (lambda () (interactive) (shell-command "xdotool key alt+x && xdotool type 'imenu' && xdotool key Return && xdotool key Tab && xdotool key F4 && xdotool key ctrl+s")))

I want to quickly locate the item by fuzzy search in *Completions* buffer, Instead of pressing Tab key complete in the minibuffer

I'm not really sure what you're trying to do, but maybe this will help:

(defun foo ()
  "..."
  (interactive)
  (minibuffer-with-setup-hook #'minibuffer-complete
    (call-interactively #'imenu)))

(global-set-key (kbd "<f4>") 'foo)
