Change hotkey for autocomplete selection
提问by ack
In Eclipse, I find it pretty annoying that Enter is the hotkey that selects an item from the Content Assist/Autocomplete list. Especially in PyDev where there is no end-of-line semicolon, pressing enter for a new line will instead give me whatever is selected in the Autocomplete list.
在 Eclipse 中，我发现 Enter 是从 Content Assist/Autocomplete 列表中选择一个项目的热键，这很烦人。尤其是在没有行尾分号的 PyDev 中，按回车键换行将给我在自动完成列表中选择的任何内容。
Tab is a much better selection hotkey since I'm not likely to want a tab mid-line.
Tab 是一个更好的选择热键，因为我不太可能想要一个 tab 中线。
Any chance of changing this in Eclipse?
有机会在 Eclipse 中改变这个吗？
Using CDT, PDT, and PyDev, but interested in any solution related to Eclipse.

All key bindings in Eclipse are defined in Window -> Preferences -> General -> Keys. I don't think you can change what is used to select stuff from the autocomplete list, but you can use space to select and then Enter for new line.
Eclipse 中的所有键绑定都在Window -> Preferences -> General -> Keys 中定义。我认为您无法更改用于从自动完成列表中选择内容的内容，但您可以使用空格进行选择，然后 Enter 换行。

The autocompletion selection key(s) is editor specific. For instance in Aptana Studio, you could define set of keys for proposal selection. See e.g. Preferences/Aptana Studio/Editors/JavaScript. Since PyDev shares some code with Aptana Studio, it has similar capabilities. See "Preferences/PyDev/Editor/Code Completion/Apply completion on *" checkboxes.
自动完成选择键是特定于编辑器的。例如，在 Aptana Studio 中，您可以为提案选择定义一组键。参见例如首选项/Aptana Studio/Editors/JavaScript。由于 PyDev 与 Aptana Studio 共享一些代码，因此它具有类似的功能。请参阅“首选项/PyDev/编辑器/代码完成/在 * 上应用完成”复选框。
Speaking of the Tab key as a selector, it doesn't seem possible w/o extra coding since it has special meaning to focus into proposals window. For these who interested could find Tab handling at org.eclipse.jface.text.contentassist.CompletionProposalPopup.verifyKey(VerifyEvent)
说到作为选择器的 Tab 键，它似乎不可能没有额外的编码，因为它具有特殊的意义，可以聚焦到建议窗口。对于那些感兴趣的人可以在 org.eclipse.jface.text.contentassist.CompletionProposalPopup.verifyKey(VerifyEvent) 找到 Tab 处理

Unfortunately it's not really possible to use tab instead of enter to auto-complete in PyDev (nor in Eclipse itself).
不幸的是，在 PyDev（也不在 Eclipse 本身）中使用 tab 而不是 enter 来自动完成是不可能的。
So, what I do in these cases is use Shift-Enter to go to a new line: note that in this case, you can press Shift+Enter from any place in your line and it'll mimic a 'go to end of line, press enter' (which is a nice thing for me).
因此，在这些情况下，我所做的是使用 Shift-Enter 转到新行：请注意，在这种情况下，您可以从行中的任何位置按 Shift+Enter，它会模仿“转到行尾” ，按回车'（这对我来说是件好事）。
Implementation note: as Max pointed out, the '\t' and '\r,'\n' cases are actually hard-coded in Eclipse at: org.eclipse.jface.text.contentassist.CompletionProposalPopup.verifyKey(VerifyEvent) so, to fix that, you'd need a patch which changed that at Eclipse itself (so, if you feel it's worthwhile, create a bug-request in Eclipse itself to ask for that feature).
实施说明：正如 Max 所指出的，'\t' 和 '\r,'\n' 情况实际上是在 Eclipse 中硬编码的：org.eclipse.jface.text.contentassist.CompletionProposalPopup.verifyKey(VerifyEvent) 所以，要解决这个问题，您需要一个补丁来更改 Eclipse 本身（因此，如果您认为值得，请在 Eclipse 本身中创建一个错误请求以请求该功能）。

If you have a Mac, you can download the Better Touch Tool(BTT) and change the hotkey to tab. Just tried and it worked, however if you do this you can't use the tab-key to tab regularly with the text. Which is pretty good to be able to bo. I changed it to shift+space.
如果您有 Mac，您可以下载 Better Touch Tool(BTT) 并将热键更改为选项卡。刚刚尝试过，它奏效了，但是如果你这样做，你就不能使用 tab 键定期使用文本进行 tab。能够博是相当不错的。我把它改成了shift+space。
In BTT, select Keybord in the menu between Trackpads and Apple remote. Add eclipse with the + sign on the left side. Then press +Add new shortcut. In keybord shortcut press the hotkey or combination you want. In Trigger Other keybord Shortkey press ctrl+space and you are done! Just be sure that the new shortcut is enabled in the right corner.
在 BTT 中，在触控板和 Apple 遥控器之间的菜单中选择键盘。使用左侧的 + 号添加 eclipse。然后按+添加新快捷方式。在键盘快捷键中按您想要的热键或组合。在 Trigger Other keybord Shortkey 按 ctrl+space 就完成了！只需确保在右上角启用了新的快捷方式。
