from this link http://forums.netbeans.org/ntopic21825.html The code is:
cut-to-clipboard "/*" paste-from-clipboard "*/"
And assigned it the shortcut Ctrl+Shift+Q. It works.
But i tried a lot to write a macro to uncomment the block of code
(Will remove block comment i.e /* ...*/).
But it did not work. how can i write the macro?
