zoom.cfg和global-zoom.cfg提供字体大小更改绑定(来自EmacsWiki)

C——或C-mousewheel-up:增大字体大小。 C-+或C-鼠标滚轮向下:减小字体大小。 C-0将字体大小恢复为默认值。

(set-face-attribute 'default nil :height 100)

这个值的单位是1/10pt，所以100会给你10pt，以此类推。

在AquaMacs CMD +和CMD -中调整当前缓冲区的字体大小。

在NTEmacs 23.1中，选项菜单有一个“设置默认字体…”选项。

M-x自定义脸RET默认将允许您设置脸的默认脸，所有其他脸的基础上。在这里你可以设置字体大小。

这是我的。emacs中的内容。实际上，color-theme会设置基础，然后我的自定义面部设置会覆盖一些东西。定制的set-faces是由emacs的定制面机制编写的:

;; my colour theme is whateveryouwant :)
(require 'color-theme)
(color-theme-initialize)
(color-theme-whateveryouwant)

(custom-set-faces
  ;; custom-set-faces was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 '(default ((t (:stipple nil :background "white" :foreground "black" :inverse-video nil :box nil :strike-through nil :overline nil :underline nil :slant normal :weight normal :height 98 :width normal :foundry "unknown" :family "DejaVu Sans Mono"))))
 '(font-lock-comment-face ((t (:foreground "darkorange4"))))
 '(font-lock-function-name-face ((t (:foreground "navy"))))
 '(font-lock-keyword-face ((t (:foreground "red4"))))
 '(font-lock-type-face ((t (:foreground "black"))))
 '(linum ((t (:inherit shadow :background "gray95"))))
 '(mode-line ((t (nil nil nil nil :background "grey90" (:line-width -1 :color nil :style released-button) "black" :box nil :width condensed :foundry "unknown" :family "DejaVu Sans Mono")))))

这里有一个交互调整字体高度的选项，一次一点:

;; font sizes
(global-set-key (kbd "s-=")
                (lambda ()
                  (interactive)
                  (let ((old-face-attribute (face-attribute 'default :height)))
                    (set-face-attribute 'default nil :height (+ old-face-attribute 10)))))

(global-set-key (kbd "s--")
                (lambda ()
                  (interactive)
                  (let ((old-face-attribute (face-attribute 'default :height)))
                    (set-face-attribute 'default nil :height (- old-face-attribute 10)))))

当您想要调整所有缓冲区中的文本大小时，这是可取的。我不喜欢使用文本比例增加和文本比例减少的解决方案，因为排水沟中的行号之后会被切断。
