Menu
Hi how can I colorize the emacs buffer menu, I'd like to have different colors for different type of files. That should make it easier to navigate a large list of buffers.

To change the foreground or background color in Emacs through the windowing interface, you can use the menu commands Foreground Color->Other and Background Color->Other in the Edit->Text Properties menu.
This is because Emacs tracks buffer positions using that data type. For typical 64-bit machines, this maximum buffer size is 2^{61} - 2 bytes, or about 2 EiB. For typical 32-bit machines, the maximum is usually 2^{29} - 2 bytes, or about 512 MiB.
Buffers in Emacs editing are objects that have distinct names and hold text that can be edited. Buffers appear to Lisp programs as a special data type. You can think of the contents of a buffer as a string that you can extend; insertions and deletions may occur in any part of the buffer.
If you want to create a buffer that contains a file, simply type C-x C-f to find the file. Emacs automatically creates a second buffer and moves you there. If you already have a copy of the file in a buffer, C-x C-f just moves you to the existing buffer.
Try M-xibuffer. It can serve as a replacement for list-buffers(C-x C-b), with a wealth of extra functionalities for filtering, sorting, etc. After invocation, use C-h m for more details.

See EmacsWiki, it contains some links to enhanced buffer menus.

Or you can find your best Keybind:
(global-set-key (kbd "C-x C-b") 'buffer-menu)
instead C-x C-b if you have another better choice.
