— Command: exit-minibuffer

This command exits the active minibuffer. It is normally bound to keys in minibuffer local keymaps.

— Command: self-insert-and-exit

This command exits the active minibuffer after inserting the last character typed on the keyboard (found in last-command-char; see Command Loop Info).

— Command: previous-history-element n

This command replaces the minibuffer contents with the value of the nth previous (older) history element.

— Command: next-history-element n

This command replaces the minibuffer contents with the value of the nth more recent history element.

— Command: previous-matching-history-element pattern

This command replaces the minibuffer contents with the value of the previous (older) history element that matches pattern (a regular expression).

— Command: next-matching-history-element pattern

This command replaces the minibuffer contents with the value of the next (newer) history element that matches pattern (a regular expression).

— Function: minibuffer-prompt

This function returns the prompt string of the currently active minibuffer. If no minibuffer is active, it returns nil.

— Function: minibuffer-prompt-width

This function returns the display width of the prompt string of the currently active minibuffer. If no minibuffer is active, it returns 0.

— 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).

— Function: active-minibuffer-window

This function returns the currently active minibuffer window, or nil if none is currently active.

— Function: minibuffer-window &optional frame

This function returns the minibuffer window used for frame frame. If frame is nil, that stands for the current frame. Note that the minibuffer window used by a frame need not be part of that frame—a frame that has no minibuffer of its own necessarily uses some other frame's minibuffer window.

— Function: window-minibuffer-p &optional window

This function returns non-nil if window is a minibuffer window.

— Function: minibuffer-window-active-p window

This function returns non-nil if window, assumed to be a minibuffer window, is currently active.

— 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-depth

This function returns the current depth of activations of the minibuffer, a nonnegative integer. If no minibuffers are active, it returns zero.

— User Option: enable-recursive-minibuffers

If this variable is non-nil, you can invoke commands (such as find-file) that use minibuffers even while the minibuffer window is active. Such invocation produces a recursive editing level for a new minibuffer. The outer-level minibuffer is invisible while you are editing the inner one.

This variable only affects invoking the minibuffer while the minibuffer window is selected. If you switch windows while in the minibuffer, you can always invoke minibuffer commands while some other window is selected.
