配置 VSCode 使之不只用 Tab 跟回车键确认输入一个智能提示项

最近 VSCode 终于推出 1.0 正式版了。下载安装之后，发现默认只能用 Tab 跟回车来确认输入一个智能提示项，这用惯 Visual Studio C# 的我感到无比痛苦。

然而，在 VSCode 里面，连配置快捷键都是用代码的，json 格式，找不到像 VS 里面类似下面的那种选项：

网上搜了一轮，只找到问同样的问题的人而没有答案，只好自己慢慢挖掘了。经过千辛万苦，最后发现在默认的 keybindings.json 配置文件几乎最下方找到了线索：

{ "key": ".",
  "command": "^acceptSelectedSuggestion",
  "when": "editorTextFocus && suggestWidgetVisible && editorLangId == 'typescript' && suggestionSupportsAcceptOnKey" },

这就是在说，在编辑器中用户按了 “.” 之后，如果 when 后面的条件成立，那么就执行 “^接受所选的建议项”，前面的 “^” 是指，接受的建议项应该加在用户敲的 “.” 之前。打个比方，当用户输入 ab.（注意最后的点），而此时建议项是 abc，那么最终结果是 abc.

明白这个以后，就可以将一大堆可接受 commit character 的配置成这样了，最终我的 keybindings.json 长这样：
