Hi there, I'd like the option to unbind default keybindings. Specifically, the Ctrl+W to close a tab binding. I reflexively hit ctrl+W when I want to delete a word in a text box (from emacs/shell/vim/etc) and this has resulted several times in me closing the tab I was on and losing the text I was writing. It would be useful to me to be able to disable this keybinding so that I don't continue having these accidents. More generally, I imagine that some users will find some keybindings annoying and want to disable or maybe remap them.

So this is half a feature request, and also half a support request if anyone has suggestions for workarounds in the meantime.
