How to delete/change built in system wide keyboard shortcuts

[soupdiver]

I'm using Divvy to arrange my windows. I have a macbook that I upgraded vom previous version. There I could bind OPTION + left for example.
Now I have a new macbook and there I can not do that anymore. It tells me this shortcut is a system wide one and can't be assigned. I should check the keyboard settings but in there I can not tind this particular one.
Any ideas how to change or get rid of those "hidden" built in shortcuts?

As the alert tells you, change it in the Keyboard & Mouse panel in System Preferences / Settings.

I don't think this particular one can be disabled via system preferences? It's a core text navigation shortcut.
Regardless an event tap can always intercept it, so I'm not sure why divvy doesn't allow you to bind it.

As @f54da already mentioned, Opt-left arrow is a core text navigation (I think it's part of emacs that came from Unix). I don't know why Divvy doesn't allow you to redefine this shortcut (KeyboardMaestro can, for example). Maybe Divvy doesn't want to bypass some security restrictions.

But regardless, this is actually quite a useful built-in shortcut that you may not want to overwrite. It jumps one word left when you navigate text (and if you add Shift, it will add a word to your selection). Opt-right arrow does a similar thing. Other useful shortcuts are Cmd-right/left arrow that allow you to jump to the end/start of the line.

P.S. There's a way to overwrite these shortcuts using the "DefaultKeyBinding.dict" file; I was playing with it many years ago and don't remember the details; try to google it for more info if it's important.
