When I'm writing code and need to define a string, I find it quite discomforting that I have to type two quotes. This is because many current IDEs and editors automatically complete double and single quotes. When I define a string, I only need to type one quote and the other is automatically filled in.
The summary of functions is as follows.：
1. Automatically complete double and single quotation marks. When you input a quotation mark, it will automatically add the matching one after the cursor position. Pressing the tab key inside the quotation marks allows you to exit them. This feature can also be disabled.
2. Automatically add the matching right parenthesis when you input a left parenthesis, similar to the auto-completion feature for quotes.
