配置 VSCode 使之不只用 Tab 跟回車鍵確認輸入一個智能提示項

最近 VSCode 終於推出 1.0 正式版了。下載安裝之后，發現默認只能用 Tab 跟回車來確認輸入一個智能提示項，這用慣 Visual Studio C# 的我感到無比痛苦。

然而，在 VSCode 里面，連配置快捷鍵都是用代碼的，json 格式，找不到像 VS 里面類似下面的那種選項：

網上搜了一輪，只找到問同樣的問題的人而沒有答案，只好自己慢慢挖掘了。經過千辛萬苦，最后發現在默認的 keybindings.json 配置文件幾乎最下方找到了線索：

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

這就是在說，在編輯器中用戶按了 “.” 之后，如果 when 后面的條件成立，那么就執行 “^接受所選的建議項”，前面的 “^” 是指，接受的建議項應該加在用戶敲的 “.” 之前。打個比方，當用戶輸入 ab.（注意最后的點），而此時建議項是 abc，那么最終結果是 abc.

明白這個以后，就可以將一大堆可接受 commit character 的配置成這樣了，最終我的 keybindings.json 長這樣：

// Place your key bindings in this file to overwrite the defaults

        "key": "shift+9", // (
        "command": "^acceptSelectedSuggestion",

保存一下，搞定。
