敲计算机或打字机上的退格键。
不过经验告诉我们，退格键不会那样。
Experience tells us that Backspace does nothing of the sort.
我多希望嘴上有个退格键。
退格键实际上是一个撤销功能，虽然它非常特殊。
The Backspace key is really an Undo function, albeit a special one.
当用户输入错误时，可以按退格键“撤销”错误的字符。
When a user mistypes, the Backspace key "undoes" the erroneous characters.
使用不可打印的字符(例如退格键或暂停)可以提高密码的模糊度。
Requiring nonprintable characters, such as backspace or pause, is a simple way to add another layer of obfuscation to your password.
火狐中你可以设置退格键是返回前一页啊，还是页面向上滚动一页。
In Firefox, you can set your backspace to better use by getting it to either go back to the previous page or act as page up function.
感觉不方便的的地方就是使用了FLASH的透明，退格键失效了。
The feeling of the place is inconvenient to use the FLASH transparent, Backspace to the failure.
可以缺省地使用光标和退格键来移动和编辑输入行，就象在Bashshell中一样。
By default you can use the cursor keys, and backspace, to move around and edit the input line, just like with the Bash shell.
我看过HTML表单，光标从一个输入字段自动移动到另一个输入字段，并使用退格键移动到上一个字段。
I have seen HTML forms whereby the cursor moves from one input field to another automatically and USES backspace to move to the previous field.
你也可以认为这对于用户来说是一个陷阱，因为他可以移动光标并且无意中用退格键删除字符，而这些字符不是最后输入的。
You could also see it as a trap for users because they can move the cursor and inadvertently backspace away characters that were not the last ones keyed in.
假如您不小心写错或者画错了某些东东，您可以用常见的ctrl+z快捷键来撤销先前的操作步骤；用退格键可以移去您在页面上所作的注释。
If you make a mistake, you can use the usual keyboard shortcuts -- ctrl+z will undo your previous action while the backspace key will remove the element from the page.
如果更多的程序有着模型化的撤销工具，用户会很快习惯它们，他们甚至会更加期望在其他软件中找到类似于字处理程序中的退格键工作方式。
If more programs had modal undo tools users would soon adapt to them. they would even come to expect them the way they expect to find the backspace key on word processors.
