putty与emacs

    win环境下putty登录到linux并使用emacs时，需要折腾好配置才能正常工作。下面是折腾过程中碰到的问题与解决步骤：

    1）要在putty控制台中启用鼠标，只需要在.emacs配置文件中启用xterm-mouse-mode：

(xterm-mouse-mode t)

    这样在控制台中点击emacs菜单时，就会看到出现一个buffer，提示对应的菜单选项。

    2）右Alt键失效问题：我参考了emacs-wiki上的文章：https://www.emacswiki.org/emacs/PuTTY

    建立文本文件fix-alt-key.reg，写入：

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,38,00,38,e0,00,00,00,00

    双击执行即可。

    3）有些功能键，如Home，End，Fn等不能正常工作。先是将putty中的keyboard类型设置为SCO，这是唯一可以识别所有功能键的模式。接着在.emacs文件中增加如何键映射配置：

(if (eq system-uses-terminfo t)
    (progn                              ;; PuTTY hack - needs to be in SCO mode
      (define-key key-translation-map [\e] [\M])
      (define-key input-decode-map "\e[H" [home])
      (define-key input-decode-map "\e[F" [end])
      (define-key input-decode-map "\e[D" [S-left])
      (define-key input-decode-map "\e[C" [S-right])
      (define-key input-decode-map "\e[A" [S-up])
      (define-key input-decode-map "\e[B" [S-down])
      (define-key input-decode-map "\e[C" [S-right])
      (define-key input-decode-map "\e[I" [prior])
      (define-key input-decode-map "\e[G" [next])
      (define-key input-decode-map "\e[M" [f1])
      (define-key input-decode-map "\e[Y" [S-f1])
      (define-key input-decode-map "\e[k" [C-f1])
      (define-key input-decode-map "\e\e[M" [M-f1])
      (define-key input-decode-map "\e[N" [f2])
      (define-key input-decode-map "\e[Z" [S-f2])
      (define-key input-decode-map "\e[l" [C-f2])
      (define-key input-decode-map "\e\e[N" [M-f2])
      (define-key input-decode-map "\e[O" [f3])
      (define-key input-decode-map "\e[a" [S-f3])
      (define-key input-decode-map "\e[m" [C-f3])
      (define-key input-decode-map "\e\e[O" [M-f3])
      (define-key input-decode-map "\e[P" [f4])
      (define-key input-decode-map "\e[b" [S-f4])
      (define-key input-decode-map "\e[n" [C-f4])
      (define-key input-decode-map "\e\e[P" [M-f4])
      (define-key input-decode-map "\e[Q" [f5])
      (define-key input-decode-map "\e[c" [S-f5])
      (define-key input-decode-map "\e[o" [C-f5])
      (define-key input-decode-map "\e\e[Q" [M-f5])
      (define-key input-decode-map "\e[R" [f6])
      (define-key input-decode-map "\e[d" [S-f6])
      (define-key input-decode-map "\e[p" [C-f6])
      (define-key input-decode-map "\e\e[R" [M-f6])
      (define-key input-decode-map "\e[S" [f7])
      (define-key input-decode-map "\e[e" [S-f7])
      (define-key input-decode-map "\e[q" [C-f7])
      (define-key input-decode-map "\e\e[S" [M-f7])
      (define-key input-decode-map "\e[T" [f8])
      (define-key input-decode-map "\e[f" [S-f8])
      (define-key input-decode-map "\e[r" [C-f8])
      (define-key input-decode-map "\e\e[T" [M-f8])
      (define-key input-decode-map "\e[U" [f9])
      (define-key input-decode-map "\e[g" [S-f9])
      (define-key input-decode-map "\e[s" [C-f9])
      (define-key input-decode-map "\e\e[U" [M-f9])
      (define-key input-decode-map "\e[V" [f10])
      (define-key input-decode-map "\e[h" [S-f10])
      (define-key input-decode-map "\e[_" [C-f10])
      (define-key input-decode-map "\e\e[V" [M-f10])
      (define-key input-decode-map "\e[W" [f11])
      (define-key input-decode-map "\e[i" [S-f11])
      (define-key input-decode-map "\e[u" [C-f11])
      (define-key input-decode-map "\e\e[W" [M-f11])
      (define-key input-decode-map "\e[X" [f12])
      (define-key input-decode-map "\e[j" [S-f12])
      (define-key input-decode-map "\e[v" [C-f12])
      (define-key input-decode-map "\e\e[X" [M-f12])))

    这之后功能键就能正常识别了。putty的文档可以看这里：http://the.earth.li/~sgtatham/putty/0.62/htmldoc/Chapter4.html#config-keyboard

    以上问题解决后，putty中使用emacs就没有什么大问题了。不过我发现【CTRL-数字-键位】时无法执行，【CTRL-数字】被解释成了其它的功能。此点还需要进一步调查。
