👍 Thanks @Leano1998 ! I gave this a try today, and it works well. I initially realized that sometimes this hamburger menu is working for me on sandbox.dspace.org and demo.dspace.org...but it also does hang at times. This change to use keydown appears to stabilize it (I no longer can reproduce the hanging behavior).

Tested in Chrome, Firefox, and Edge. All work well.
