    Since the minibuffer appears in the echo area, it can conflict with
  other uses of the echo area.  If an error message or an informative
- message is emitted while the minibuffer is active, the message hides
- the minibuffer for a few seconds, or until you type something; then
- the minibuffer comes back.  While the minibuffer is in use, Emacs does
- not echo keystrokes.

 +  While using the minibuffer, you can switch to a different frame,
 +perhaps to note text you need to enter (@pxref{Frame Commands}).  By
 +default, the active minibuffer moves to this new frame.  If you set
 +the user option @code{minibuffer-follows-selected-frame} to
 +@code{nil}, then the minibuffer stays in the frame where you opened
 +it, and you must switch back to that frame in order to complete (or
 +abort) the current command.  If you set that option to a value which
 +is neither @code{nil} nor @code{t}, the minibuffer moves frame only
 +after a recursive minibuffer has been opened in the current command
 +(@pxref{Recursive Mini,,, elisp}).  This option is mainly to retain
 +(approximately) the behavior prior to Emacs 28.1.  Note that the
 +effect of the command, when you finally finish using the minibuffer,
 +always takes place in the frame where you first opened it.  The sole
 +exception is that when that frame no longer exists, the action takes
 +place in the currently selected frame.
