Undo shortcut not working in Eclipse
提问by denispyr
The last couple of days the Ctrl+Zshortcut (Undo) scrolls down a line (a-la emacs). I tried to switch schemes back and forth, change and redefine the Undo in Default scheme, nothing seems to work. Other combinations (Alt+Ctrl+Z) work fine, other workspaces work fine with Ctrl+Z.
最近几天Ctrl+Z快捷方式 (Undo) 向下滚动一行 (a-la emacs)。我试图来回切换方案，更改并重新定义默认方案中的撤消，似乎没有任何效果。其他组合 ( Alt+ Ctrl+ Z) 工作正常，其他工作区与Ctrl+一起工作Z。
Any tip that will save me from redefining the workspace?
有什么技巧可以让我免于重新定义工作区？

The key bindings are stored in the file [workspace]\.metadata\.plugins\org.eclipse.e4.workbench\workbench.xmi.
键绑定存储在文件中[workspace]\.metadata\.plugins\org.eclipse.e4.workbench\workbench.xmi。
You can search for Ctrl+Zin this file. What does it look like? You could try to edit it by hand.
您可以Ctrl+Z在该文件中搜索。它是什么样子的？您可以尝试手动编辑它。
Of course, it is advisable to backup the workspace before.
当然，建议之前备份工作区。

From time to time, I have encountered similar issues with keyboard shortcuts. They just disappear, or doesn't seem to work as expected.
我不时遇到键盘快捷键的类似问题。它们只是消失了，或者似乎没有按预期工作。
Until I figure out what the root cause is, I check key bindings.
在找出根本原因之前，我会检查键绑定。
Window > Preferences > General > Keys
Check if the key bindings are still valid. If not, then set them and it should work.
检查键绑定是否仍然有效。如果没有，然后设置它们，它应该可以工作。

Window > Preferences > General > Keys Look for Undo in the list, if the Binding is empty click on Restore Command apply and close. That should enable the shortcut.
Window > Preferences > General > Keys 在列表中寻找 Undo，如果 Binding 为空，点击 Restore Command apply 并关闭。那应该启用快捷方式。
