VS2017自动补全（Auto-Completion）快捷键修改及输入问题咨询

Hey there, I’ve fought through these exact VS2017 input annoyances before—let’s get them sorted out for you step by step!

1. Switch Auto-Completion Confirm Key from TAB to Enter #

To make Enter confirm the highlighted completion item directly (no need to press Down first), follow these steps:

• Open VS2017, go to the top menu bar and click Tools → Options
• In the Options window, expand Text Editor → select your target language (e.g., C/C++, C#; pick All Languages if you want this change across all supported languages)
• Expand IntelliSense and choose General
• Look for the Commit completion with setting: change it from the default Tab only to Enter and Tab
• Make sure the Preselect most relevant item option is checked—this ensures the best-matching completion is automatically highlighted when you type a prefix, so you can just hit Enter to confirm right away

2. Fix Missing Auto-Added Parentheses for Functions #

This one’s usually a simple settings tweak too:

• Head back to Tools → Options → Text Editor → your target language → IntelliSense → General
• Double-check that both Auto list members and Parameter information are enabled (checked)
• For language-specific fixes (like C++), navigate to Text Editor → C/C++ → Advanced, then ensure Disable IntelliSense is set to No
• If the issue persists, try refreshing the IntelliSense cache: go to Edit → IntelliSense → Refresh Local Cache, then restart VS2017 to apply changes

Give these steps a shot—they should make your coding flow in VS2017 feel way more natural!
