(But <f1>, <f3>, <f4>, <f10>, <f11> are not, by default,
prefix keys.)

<f1> is bound to `help-command', which is a prefix command, and
`C-h f help-command' tells you its definition is a keymap.  But
`<f1> C-h' doesn't tell you about keys with prefix <f1>.  `C-h b'
shows those keys, however.  And `C-h k <f1>' shows you that it's
a prefix command by waiting for you to type another key, to
complete the key sequence.

The others I listed are bound to simple commands.  They're not
prefix keys.  `C-h k' tells you about each one.
