帮助一百万开发者退出 Vim
Helping a Million Developers Exit Vim
2017 — 2019，它一次次回到首页
黑点是上首页（≥ 50 分）的那次投稿，空心点是没冲上去的投稿，点越大分数越高。
导读
这是 Stack Overflow 官方博客的一篇文章，介绍其史上浏览量最高的经典问题——“如何退出 Vim”——累计帮助了约一百万开发者。文章借此回顾了这个广为流传的程序员梗，并探讨了 Vim 的模式化设计为何让新手如此困惑。
为什么经久不衰：“如何退出 Vim”是程序员文化中最经典的共同记忆之一，文章既有趣味性也引发对界面设计与学习曲线的思考，多年后依然能引起共鸣。

陡峭的学习曲线不等于糟糕的设计，掌握后效率极高
我做了近十年 IT，公司后端完全基于 AS/400。那种控制台学习曲线很陡，没法凭直觉上手，但一旦掌握，你一辈子都找不到比它更快的界面。新人总坚持要换成鼠标操作的界面，却不知道“更直观”其实是退步。我的观点是：学习曲线陡峭不代表设计糟糕。

I spent almost 10 years doing IT for a company whose backend was based entirely on as/400. If you've ever used a system like that, I'm sure you know where this is going... The console's that the front-desk or clerical users used every day had a steep learning curve. It was something that you would definitely not be able to walk up to and just intuit. However, once you figured it out, there is never going to be a faster UI that you are ever going to experience in your life until we figure out direct BCI stuff. It was funny watching the new people come on board and insist that we should change the UI to something with a mouse (probably web based). They had no idea that more immediately intuitive was actually a step backwards. My point is that just because something has a steep learning curve, that doesn't necessarily mean that it's a bad design.
Unix 下退出方式五花八门，对新手极不友好
这可能是 Unix 系统对新用户最大的问题：退出一个命令行程序的方式太多了！Ctrl+D、q、:q、exit、quit()、Ctrl+C、Ctrl+X……我无数次被困在程序里，只能挨个试这些背下来的命令。想象一下新手面对这种情况。

This is probably the #1 problem with Unix-based systems in general for new users. There are so many ways to exit a command prompt depending on the application! Off the top of my head: Ctrl+D, q, :q, exit, quit(), Ctrl+C, Ctrl+X. Countless times have I been locked in an application and needed to cycle through those memorized commands to escape. Imagine doing that as a newbie.
Vim 启动不在编辑模式，违背新手直觉，导致大量卡死
读研第一年我当助教，第一节课整个实验时间都在到处帮学生解救卡死的 vi。主要问题是 vi 启动时不在编辑模式，学生以为可以直接打字（这是合理的预期），结果不知触发了什么命令，有时我干脆 ctrl-z 然后 killall vi。我因此恨透了 vi。

My first year of grad school I was a TA for a first year computer science course that was often taken by students from a variety of majors. The first editing sessions I spent the whole lab time running around help students with frozen vi editors. The main problem is you don't start in "edit mode" and students expect to be able to just start typing (which is a reasonable expectation). Who knows what "command" they just invoked -- sometimes I just "ctrl-z, killall vi" I learned to hate vi.
当年键盘布局不同（ESC 在 F11），也是新手被困 vi 的历史原因
我认识我妻子就是因为她被困在 vi 里。90 年代初我是 Unix 系统管理员，她是研究生，来找我问怎么退出 vi。其实她会用 vi，只是找不到 ESC 键——DEC 键盘上 ESC 是 F11。所以新生第一周问我问题时，我答“F11”，90% 都是对的。

I met my wife because she was stuck in VI. I was a unix sysadmin in the early 90s, and she was a grad student. She came to me for help (like most of the 1st years did) because she couldn't get out of vi. However, to be fair, this was not her fault per-say. She actually knew how to use vi, but just couldn't find the ESC key. Does anybody remember the DEC keyboards where there was no traditional ESC key, but it was F11? (http://www.cosam.org/images/vt220/keyboard.jpg). Yeah, we used DECstations in the grad labs, and whenever a new grad student asked me a question in the 1st week, I'd answer "F11", and 90% of the time I was right.
