I found in settings you can change the function of different keys, however I don't know how you can change combinations. For example I'm not sure what option + forward slash is doing exactly, but whenever I press it, it messes up a lot of my code. Then I press Ctrl Z to undo but it seems to break more. How do I disable a specific key combination?
Change a conflicting keyboard shortcut on Mac
It’s possible to have a keyboard shortcut that performs a different action depending on which app you’re using.
For example, Command-Space bar opens the Spotlight menu, but in another app it might do something else. You can change conflicting keyboard shortcuts so the same shortcut doesn’t perform different actions in different apps.
Note: Keyboard shortcuts in apps may vary depending on the language and keyboard layout you’re using on your Mac. If shortcuts don’t work as you expect, look in the app menus in the menu bar to see the correct shortcuts. You can also use the Keyboard Viewer to see your current keyboard layout, known as an input source.

Conbinations of Option plus charcter are reserved for special characters by MacOS. With the US keyboard, option / will normally produce ÷. What is it that you want this to do instead?
Your are welcome
As for the followup addressed to my learned colleague.
I am very confident they should be abbe to offer some insights 😎
Option would not delete anything in an apple app, just print divide. Best ask in a Colab support forum how others have dealt with the problem.
It is Google Colab. I found when I press option in general just on its own in Google Colab, it deletes some random amount of code (without me having highlighted it) and adds a divide char as well. I cant seem to figure out the pattern. Is this something Colab can control or is this Mac controlling the option key here?
Thank you for your detailed explanation. I think the issue is actually application specific. Specifically Google Colab. I realized that from your answer. That should hopefully solve my problem.
Thank you for the clarification
