Hello! It sounds like you’re having trouble with the delete and backspace keys in Collabora Office. Let's work through this issue together.

To better assist you, could you please let me know if this issue occurs in a specific document or all documents? Additionally, are you using any particular extensions or custom settings that might affect key functionalities?

In the meantime, here are some general troubleshooting steps you can try:

1. Refresh the Document: Sometimes, simply refreshing the document can resolve minor glitches. Try closing and reopening the document to see if the keys start responding.

2. Check Your Keyboard: Ensure that your keyboard is functioning properly. You can test it in another application (like Notepad) to see if the delete and backspace keys work there.

3. Clear the Cache: If you are using Collabora Office in a web browser, clearing your browser's cache might help. Here is how to do it:
- Open your browser settings.
- Look for 'Privacy and Security.'
- Choose 'Clear browsing data' and select cached images and files, then confirm.

4. Try a Different Browser: Since you’re using Windows with WebKit, it would be worthwhile to test Collabora Office in another browser (like Chrome or Firefox) to see if the issue persists.

5. Update Collabora Office: Ensure you are using the latest version of Collabora Office. Outdated versions can sometimes lead to unexpected behavior.

If none of these steps helps, we may need to delve deeper into the issue or look for specific updates related to this behavior in Collabora Office. Please let me know how it goes!
