title: How to enter minibuffer for editing in Emacs?
body: <p>When running certain commands, the mini-buffer asks input strings, (e.g. the C-M-s). </p>
  
  <p>Sometimes I need to enter complex strings into minibuffer. Therefore, I need to use movement commands such as C-f, C-b, C-a, etc. However, these does not work when I am entering string inside command <kbd>C-M-s</kbd>. </p>
  
  <p>So, what is the general command / key-bindings for me to focus point in mini-buffer for extended movement support? </p>

  <p>Edit:</p>
  
  <p>I just discovered that M-e will work for searching commands. But I am not sure whether this command is the general command to "switch from buffer to minibuffer for dedicated editing"</p>
