如何在 eclipse ant 编辑器中启用撤消? [英] How do I enable undo in eclipse ant editor?

问题描述

在 Eclipse 的 ant 编辑器中，撤消对我不起作用.当我按 Ctrl-Z 时什么也没有发生.

Undo is not working for me in ant editor in eclipse. When I press Ctrl-Z nothing happens.

是否可以以某种方式启用撤消或者这是一个错误?

Is it possible to enable undo somehow or is this a bug?

我在 Windows XP Professional 上使用 Eclipse 3.4.2 (Ganymede).

推荐答案

是的，撤消应该在 ant 编辑器中完美运行.
对于 Ctrl-Z 不起作用可能意味着:

Yes undo should be working perfectly in an ant editor.
For Ctrl-Z to not workcould mean:

• 快捷方式已分配给另一个操作(Windows > Preferences > General > Keys)
• 撤消缓冲区大小不知何故为0"(Windows > Preferences > General > Editors > Text Editor)
• 插件以某种方式窃取"了自己的关键事件

尝试全新安装，并检查最新的 Galileo (3.5RC2) 安装，看看问题是否仍然存在.

Try a fresh install, and check also with a latest Galileo (3.5RC2) install to see if the problem persist.
