[英]Squeak Smalltalk vertical arrow in code

原文 2011-10-19 10:35:21 8 2 smalltalk/ squeak

I'm trying to learn Smalltalk and so I'm doing the "Squeak by Example" tutorial. 我正在尝试学习Smalltalk，所以我正在做“Squeak by Example”教程。 I have to write a method in the system browser with a vertical arrow which points up at the beginning of the code. 我必须在系统浏览器中编写一个方法，其中一个垂直箭头指向代码的开头。 Is there a Unicode sign or something like this, which I could use in Windows? 是否有Unicode标志或类似的东西，我可以在Windows中使用？

Thanks in advance (I know, it's a very simple question, but I don't get the clue)! 在此先感谢（我知道，这是一个非常简单的问题，但我没有得到线索）！ :) :)

Vertical arrow is ^ on your keyboard. 键盘上有垂直箭头^ 。

Squeak was namely an Apple sponsored project and from Mac keyboard comes a vertical arrow. Squeak是Apple赞助的项目，Mac键盘上有一个垂直箭头。 On non-Mac computers a ^ is an equal replacement. 在非Mac计算机上， ^是一个相同的替代品。

This answer serves as a historical note on the up arrow. 这个答案是关于向上箭头的历史记录。 " The Smalltalk-76 Programming System Design and Implementation " uses up- and left-arrows. “ Smalltalk-76编程系统设计和实现 ”使用向上和向左箭头。 The " Smalltalk-72 Instruction Manual " also uses up- and left-arrows. “ Smalltalk-72使用说明书 ”也使用了向上和向左箭头。 (Notably, both use a hollow up-arrow - think an equals sign on its side and topped with a ^.) （值得注意的是，两者都使用了一个空心的向上箭头 - 在它的侧面思考一个等号并且顶部有一个^。）
