Open link in a new window by clicking CTRL+clic
As most of the browsers do, have theb option to open the link in a new tab by clicking CTRL also.
Would be to have another "keyboard shortcuts" in the main bar as:
CTRL + Enter = completes .com SHIFT + Enter = completes .net ALT + Enter = open the website in a different tab, this can be combined with the two above
And probably I'm missing a few, but this ones are the most used.
