CTRL Key

[jhonny11]

\ is easy - you hit the dot (lower left key) then / then the dot again and then space (sym) - or just hold the dot down while hitting / then space. The more you hit space the more symbols you get (it rotates through). That's true on most of the keys - you can do accents that way as well..

As for ctrl - I got nothing... You can use a program like rkeyen and assign it a shortcut. If you want copy/paste (I think the most common ctrl+key you'd use) you can use the same program to do that as well..
