  The first field of a line indicates:

  • ‘.’ the buffer is current.
  • ‘%’ a read-only buffer.
  • ‘*’ the buffer is modified.

• Select buffer. You can select out of any open buffer with the following keybinding:

  C-x b

  _{You will be prompted for the buffer name you wish to switch to.}

• List buffers:

  C-x C-b

• Save-some-buffer, giving the choice which buffer to save or not:

  C-x s

• Kill one buffer:

  C-x k

• Operations on marked buffers:

  S Save the marked buffers

  A View the marked buffers in this frame.

  H View the marked buffers in another frame.

  V Revert the marked buffers.

  T Toggle read-only state of marked buffers.

  D Kill the marked buffers.

  M-s a C-s Do incremental search in the marked buffers.

  M-s a C-M-s Isearch for regexp in the marked buffers.

  U Replace by regexp in each of the marked buffers.

  Q Query replace in each of the marked buffers.

  I As above, with a regular expression.

  P Print the marked buffers.

  O List lines in all marked buffers which match a given regexp (like the function `occur').

  X Pipe the contents of the marked buffers to a shell command.

  N Replace the contents of the marked buffers with the output of a shell command.

  ! Run a shell command with the buffer's file as an argument.

  E Evaluate a form in each of the marked buffers. This is a very flexible command. For example, if you want to make all of the marked buffers read only, try using (read-only-mode 1) as the input form.

  W - As above, but view each buffer while the form is evaluated.

  k - Remove the marked lines from the Ibuffer buffer, but don't kill the associated buffer.

  x - Kill all buffers marked for deletion.

• Save-some-buffer, giving the choice which buffer to save or not:

  C-x s

• Switch to the next buffer:

  C-x RIGHT

• Switch to previous buffer:

  C-x LEFT
