What is shortcut for comment and uncomment in Eclipse.

Sometimes, we need comment/uncomment some lines of code.
Eclipse has tones of useful shortcuts...and some of them are about comment/uncomment :)


For single line comment (//)
To comment press CTRL + /
To uncomment press  CTRL + / again.

For multi-line  line comments ( /* */)
To comment press CTRL + SHIFT +  /
To uncomment press  CTRL + SHIFT +  \ (WARNING! it is BACKSLASH not FORWARD SLASH like in single line comment)

Just in case:
 / is  a Forwards Slash
\ is a Backslash


I wonder,what were reasons behind design decision behind to use backslash instead of forward slash for multi-line comment.

Useful shortcut : Show documentation of highlighted item (method,class and etc.) in IntelliJ IDEA

One of the must have feature in any good IDE is a show documentation of highlighted  item.
Netbeans and Eclipse always display that automatically,but in Intellij IDEA you need press.... crtl + q, to see it.

It is quite uncomfortable, that you need press something instead of see it,but it is ok.
