Using Crusader cheats in DosBox

Is there a way to the invincibility cheat (CTRL+F10) to work in DosBox? CTRL+Function keys are DosBox commands, so CTRL+F10 won't work for the Crusader cheat.
Probably it will only work if you re-bind the dosbox function keys, but I dont know if thats possible or how.

Probably not even worth the effort, if you die you can push F10 again and the silencer will live again  :)
I know that, but it's very annoying when you are surrounded by rocketdude's and a thresher cannon. It's almost impossible to get out of that situation without invincibility. Really annoying when I just want to play through it very quick to check something.
