[BUG] Delete keyboard shortcut listed in docs but not working in the editor

[rounittxx]

Describe the bug
The documentation shows DEL → Delete selected element, but the shortcut does not work anywhere in the editor (tables, notes, areas, relationships).
This suggests the feature is documented but not implemented.

To Reproduce
Steps to reproduce the behavior:

1. Create any element
2. Select it
3. Press Delete
4. Nothing happens

Expected behavior
Pressing Delete removes the selected element as documented.

Hey! I’d like to work on this issue.

I’ve already reproduced the bug and confirmed that the Delete shortcut is listed in the documentation but never actually handled anywhere in the keyboard event flow. I’ve started investigating how keyboard interactions tie into the editor canvas, and I’m working on adding a proper global keydown handler that triggers the existing delete logic for all selectable elements.

Please assign this issue to me — I’ve already begun implementing a fix and will open a PR soon.Happy to collaborate or adjust the approach based on any guidance!
