How can I prevent the mini-buffer from displaying previous commands in Emacs?

I am not even sure this is a previous command or a non-finished command or whatever, but I do know I really don't like it.

My problem is that some commands (or messages, or whatever) get stuck in the mini-buffer so that when I type a new command it appears there really quickly, and then the mini-buffer is back to the stubborn command. Some commands seem to be chosen, and after usi开发者_StackOverflow社区ng lots of commands something else gets stuck there, but there is always something being shown that I don't want to see. I tried typing C-g lots of times to see if it would quit, but that does not work.

This is a picture of what I have now:

It does not matter what I do, that bit

Label: hl-line

will not leave. It does leave momentarily when a new command is typed, but it goes back. I don't like it, it is confusing, and I would much rather see there the last used command.

I did check the customisation options for the mini-buffer (the bottom part of it can be seen in my picture), but I found nothing that seemed to be what I was looking for.

Any ideas?

Chances are you're getting into the situation because you started a command and used your mouse to select something in a different window. If that's the case, you can have Emacs automatically abort the command when you do such an action.

This is the code you'd add to your .emacs:

(defun stop-using-minibuffer ()
  "kill the minibuffer"
  (when (and (>= (recursion-depth) 1) (active-minibuffer-window))
    (abort-recursive-edit)))

(add-hook 'mouse-leave-buffer-hook 'stop-using-minibuffer)

Note: I grabbed this from my blog post on the topic.

And there is also a super user question that addresses this issue, and my answer there provides a command to jump back to the minibuffer.

The mini-buffer has lost focus. Try C-x o (Control+x o) to regain focus. To cancel the command press C-g when you have focus in the mini-buffer.
