Bring intellisense when write F# query and other code

Ctrl + J is to bring the intellisense.
Ctrl +K, C is to comment out current selected code
Ctrl +K, U is to uncomment current selected code

I found Ctrl + J is very useful when writing F# queries. For example,

when you write something like:

let myQuery = query { for n in ABC do

Ctrl + J can help you find the keyword in query.
