Hey, most of you might know this, but for future reference and new users i'll post it here, so that others can find it.

I just was playing some nethack, and it has some keys bound to keys that i thought are kind of reserved to windowmanager stuff, so i wanted to have the possibility to switch to a mode in which all keys are passed on to the program and won't be picked up by i3, i think one might call that a passthrough mode. All you have to do to achieve this, is add the following to your i3 config file:

mode  "Passthrough Mode - Press Alt F12 to exit" {
        bindsym $mod F12 mode "default"
}
bindsym $mod F12 mode "Passthrough Mode - Press Alt F12 to exit"

Of course you can change the keys and the name of the mode ... :P

I'm not a native speaker and i've found it a bit difficult to describe this, so if you have any suggestions...

Cheers!
