title: Go to back directory browsing after opening file in vim
body: <p>When I open a directory browsing in vim, I can open a file by moving the cursor to a file name and pressing <kbd>Enter</kbd>. </p>
  
  <p>Now, is there any command to go back to the previous directory browsing? </p>
  
  <p>If not, is there a way to open a file without closing the directory browsing mode?</p>
