How can I see function arguments in IPython Notebook Server 3?
提问by user11094
I've recently switched to IPython Notebook 3 (3.1.0-cbccb68 to be exact), the Anaconda version. Previously when I typed a function and opened a parenthesis like this:
我最近切换到 IPython Notebook 3（确切地说是 3.1.0-cbccb68），Anaconda 版本。以前，当我键入一个函数并打开这样的括号时：
time.sleep()
and if the cursor was between the parentheses then I would get a contextual overlay menu that displayed the function arguments. Now I don't see it, and although I've searched, I can't find out how I can turn on this functionality.
如果光标在括号之间，那么我会得到一个显示函数参数的上下文覆盖菜单。现在我没有看到它，虽然我已经搜索过，但我无法找到如何打开此功能。

In 1.0, the functionality was bound to (and taband shift-tab, in 2.0 tabwas deprecated but still functional in some unambiguous cases completing or inspecting were competing in many cases. Recommendation was to always use shift-Tab. (was also added as deprecated as confusing in Haskell-like syntax to also push people toward Shift-Tab as it works in more cases. in 3.0 the deprecated bindings have been remove in favor of the official, present for 18+ month now Shift-Tab.
在1.0中，该功能被绑定到(和tab和shift-tab，在2.0tab被废弃，但仍具有功能在某些情况下，明确的完成或检查在许多情况下被竞争。建议始终使用shift-Tab. (也被添加为已弃用，因为它在类似 Haskell 的语法中令人困惑，以推动人们在更多情况下使用 Shift-Tab。在 3.0 中，已弃用的绑定已被删除，以支持官方，现已存在 18 个月以上Shift-Tab。
So press Shift-Tab.

Try Shift-Tab-Taba bigger documentation appears, than with Shift-Tab. It's the same but you can scroll down.
尝试Shift-Tab-Tab一个更大的文档出现，而不是Shift-Tab. 它是一样的，但你可以向下滚动。
Shift-Tab-Tab-Taband the tooltip will linger for 10 seconds while you type.
Shift-Tab-Tab-Tab并且在您键入时，工具提示会停留 10 秒钟。
Shift-Tab-Tab-Tab-Taband the docstring appears in the pager (small part at the bottom of the window) and stays there.
Shift-Tab-Tab-Tab-Tab并且文档字符串出现在寻呼机中（窗口底部的一小部分）并停留在那里。

Place the cursor in middle of parenthesis ()before you use shortcut.
在()使用快捷方式之前，将光标放在括号中间。
alt + tab
alt + tab
Display short document and few params
显示简短的文档和很少的参数
alt + tab + tab
alt + tab + tab
Expands document with scroll bar
用滚动条展开文档
alt + tab + tab + tab
alt + tab + tab + tab
Provides document with a Tooltip: "will linger for 10secs while you type". which means it allows you write params and waits for 10secs.
提供带有工具提示的文档：“在您键入时会停留 10 秒”。这意味着它允许您编写参数并等待 10 秒。
alt + tab + tab + tab + tab
alt + tab + tab + tab + tab
It opens a small window in bottom with option(top righ corner of small window) to open full documentation in new browser tab.
它在底部打开一个小窗口，并带有选项（小窗口的右上角）以在新的浏览器选项卡中打开完整的文档。
