An IDE independent trick (that works for all languages in the C/Java/C++/C# family) I found to comment/uncomment blocks of code fast is the following:
我发现可以快速注释/取消注释代码块的一个独立于 IDE 的技巧（适用于 C/Java/C++/C# 系列中的所有语言）如下：
int a = 5;
int b = 2;
//*
if(a < b) {
int t = a;
a = b;
b = t;
}
//*/
System.out.println("a: "+a);
Say you want to comment and uncomment the ifblock frequently. You can use the //*and //*/markers. You comment the block by removing one /in the //*part. Thus:
假设您想经常注释和取消注释if块。您可以使用//*和//*/标记。您可以通过删除一个注释块/中的//*一部分。因此：
int a = 5;
int b = 2;
/*
if(a < b) {
int t = a;
a = b;
b = t;
}
//*/
System.out.println("a: "+a);
Why this works
为什么这有效
In case the first line reads //*, it is interpreted as // *, thus you comment the *and don't comment the remainder of the block. The //*/is ignored as well since it is interpreted as // */.
如果第一行读取//*，则将其解释为// *，因此您可以注释*并且不注释块的其余部分。该//*/被忽略，以及因为它被解释为// */。
In case the first line reads /*, it is interpreted as the start of a comment block. Java searches for the corresponding end which is // */(the //is ignored).
如果第一行显示为/*，则将其解释为注释块的开始。Java 搜索相应的结尾// */（//被忽略）。

In mac, it is more stable to use command+shift+c. Sometimes, command+/ could be usable but not so stable.
在mac中，使用command+shift+c更稳定。有时， command+/ 可以使用但不是那么稳定。

Also, to have a whole block commented, can be useful the rectangular selection trick as a single "null column" rectangle where we can add any comment character we like (eg. an hash or a slash):
此外，要对整个块进行注释，将矩形选择技巧用作单个“空列”矩形可能很有用，我们可以在其中添加我们喜欢的任何注释字符（例如哈希或斜杠）：
The shortcut in Mac is Ctrl+Shift+Ras explained in this thread.
在Mac上的快捷键是Ctrl+ Shift+R中的说明这个线程。
To return to the normal selection just repeat the same shortcut.
要返回正常选择，只需重复相同的快捷方式。
