Put the cursor on emacs-version and hit C-h v. One sees:
Describe variable (default emacs-version):
Now put the cursor upon (list-load-path-shadows) and hit C-h f. One sees:
Describe function (default list-load-path-shadows):
Now put the cursor upon (list-load-path-shadows) and hit M-x. One sees just:
M-x

One should see
Execute function (default list-load-path-shadows):
