There is also Ctrl + Shift + I which I use because my F12 is bound to open up a shell prompt on my computer (just a white box really).

Though what Zel-melon said I too agree. KC3 was already deprecated in favour of KC3 Kai which has plenty more features and teams involved in the making of it all. There is probably no risk of using old and deprecated viewers but I wouldn't condone the use of one (or for any old software) either.
