Ctrl + Alt + b key combination is being hijacked on Ubuntu 16.04 Xenial.
When I press it in different programs it performs some weird hard to explain actions. One of the things it does is to remove the caret in a text area...
I've checked both "System setting > keyboard > Shortcuts" and compiz config manager and the shortcut key doesn't exist in either.
How can I disable this key combination so that I can use its functionality on Intellij?
