用于调用“GUI样式”的Emacs M-x命令，菜单 [英] Emacs M-x commands for invoking "GUI-style" menus

问题描述

问题：如何在Emacs-variant使用操作系统特定的桌面功能的情况下，找到用于在Emacs中执行基于GUI的操作的Mx等效命令？

Question: How could I find out the M-x equivalent commands for doing GUI-based operations in Emacs, in those cases where my Emacs-variant uses OS-specific desktop functionality?

背景：常规理解表示，Emacs中的所有内容都是一个命令，只要知道命令的名称，就可以通过Mx调用命令。假设此语句是正确的，在基于桌面的Emacs变体中，找到用于触发GUI样式菜单的命令名称的方法是什么？

Background: Conventional understanding states that everything in Emacs is a command, and that commands can be invoked via M-x, as long as you know the name of the command. Assuming this statement is correct, what is the way to find the name of the commands used to trigger the "GUI-style" menus in a "desktop" based Emacs variant?

例如，如果我鼠标选择文件菜单打开一个文件，操作系统特定的GUI样式文件打开对话框弹出，等待我的输入。

For example, if I were to mouse-select the File menu to open a file, the OS-specific "GUI" style file-open dialog pops up, waiting for my input.

我如何找到用于执行完全相同的事情的Mx等效命令？

How could I find out the M-x equivalent command for doing the exact same thing?

我我需要知道的，但它是指示使用：

I thought that describe-key would tell me what I needed to know, but it's indication to use:

   M-x menu-find-file-existing

不会调用GUI样式文件 - 打开对话框。

doesn't invoke the "GUI" style file-open dialog. Instead, it uses the Emacs internal non-GUI-OS-neutral variant.

推荐答案

您需要诱使Emacs认为键盘没有被使用，这不像诱骗它认为使用鼠标一样直观。 ：）

You need to trick Emacs into thinking that the keyboard was not being used, which is not as intuitive as tricking it into thinking that the mouse was used. :)

(defadvice find-file-read-args (around find-file-read-args-always-use-dialog-box act)
  "Simulate invoking menu item as if by the mouse; see `use-dialog-box'."
  (let ((last-nonmenu-event nil))
    ad-do-it))

在WinXP上的Emacs 22.2.1上测试。我相信这个范例已经存在了一段时间，所以它应该在老的Emacs上工作。没有线索，如果XEmacs工作类似或不。

Tested on Emacs 22.2.1 on WinXP. I believe the paradigm has been around for a while, though, so it should work on older Emacs. No clue if XEmacs works similarly or not.
