Powerful and heterogeneous Emacs

I accidentally saw a usage of Emacs, so I opened this heterogeneous Program . I found that I couldn't understand the shortcut keys of the menu at all. I only knew it after reading Tutorial:

Emacs commands generally involve the control key (sometimes labeled CTRL or CTL) or the meta key. on Some keyboards, the meta key is labeled alt or edit or something else (for example, on Sun keyboards, the diamond key to the left of the spacebar is Meta ). if you have no meta key, you can use ESC instead. rather than write out meta or control each time we want you to Prefix A character, we'll use the following abbreviations:

C-<CHR> means hold the control key while typing the character <CHR>. Thus, C-F wocould be: Hold the control key and Type F.
M-<CHR> means hold the meta key down while typing <CHR>. If there is no meta key, type <ESC>, release it, then type the character <CHR>.

For various file types it knows, it will display corresponding operation menus in the menu, if the extension is. CC /. CPP, a "C ++" menu will be automatically added, with comments, formatting sections, and other functions. For example, if the extension name is .htm, the menu will automatically add "html ", "SGML" has two groups of menus, including inserting some commonly used labels, such as links, images, and titles. Of course, this is only a small part of the achievements, hoping to continue learning and discovering ......

During blind touch, we found that the "context key" (next to the Windows key) on the keyboard can act as M-X, while xemacs is more suitable for general operations than Emacs.
