Emacs 24 Improvements: copy/paste, describe-char, calc keymap

Perm URL with updates: http://xahlee.org/emacs/emacs24_features.html

Linux/Emacs Copy/Paste Problem

In linux, if copy/paste doesn't work with other apps, you need to add this line:

(setq x-select-enable-clipboard t)

in GNU Emacs 24.0.93.1, that var is set to t now.

unicode info

When calling “describe-char”, now it display the char's position in the first line.

Here's emacs 23 output:

        character: m (109, #o155, #x6d)
preferred charset: ascii (ASCII (ISO646 IRV))
       code point: 0x6D
           syntax: w    which means: word
…

Here's emacs 24 output:

             position: 9198 of 11337 (81%), column: 0
            character: m (displayed as m) (codepoint 109, #o155, #x6d)
    preferred charset: ascii (ASCII (ISO646 IRV))
code point in charset: 0x6D
               syntax: w        which means: word

calc keys

“calc”'s keymapping seems to have improved.

before, supposed you have set 【Alt+z】 for undo globally. But it won't work in calc. You have to use emacs's default. Now it does.
