20.14 Minibuffer Miscellany

— Function: minibufferp &optional buffer-or-name

This function returns non-nil if buffer-or-name is a minibuffer. If buffer-or-name is omitted, it tests the current buffer.

— Variable: minibuffer-setup-hook

This is a normal hook that is run whenever the minibuffer is entered. See Hooks.

— Variable: minibuffer-exit-hook

This is a normal hook that is run whenever the minibuffer is exited. See Hooks.

— Variable: minibuffer-help-form

The current value of this variable is used to rebind help-form locally inside the minibuffer (see Help Functions).

— Variable: minibuffer-scroll-window

If the value of this variable is non-nil, it should be a window object. When the function scroll-other-window is called in the minibuffer, it scrolls this window.

— Function: minibuffer-selected-window

This function returns the window that was selected when the minibuffer was entered. If selected window is not a minibuffer window, it returns nil.

— User Option: max-mini-window-height

This variable specifies the maximum height for resizing minibuffer windows. If a float, it specifies a fraction of the height of the frame. If an integer, it specifies a number of lines.

— Function: minibuffer-message string &rest args

This function displays string temporarily at the end of the minibuffer text, for a few seconds, or until the next input event arrives, whichever comes first. The variable minibuffer-message-timeout specifies the number of seconds to wait in the absence of input. It defaults to 2. If args is non-nil, the actual message is obtained by passing string and args through format. See Formatting Strings.

— Command: minibuffer-inactive-mode

This is the major mode used in inactive minibuffers. It uses keymap minibuffer-inactive-mode-map. This can be useful if the minibuffer is in a separate frame. See Minibuffers and Frames.
