Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

Beeps and text ;3D or ;3C appears

To Reproduce

At the terminal, press option+left cursor, or option+right cursor (or on a Windows style keyboard, alt+left and alt+right).

Configuration

no config

Expected Behavior

Cursor jumps one word left, or right (as on Apple Terminal and others).

Logs

Anything else?

I have a UK keyboard layout. I have tested this on two different machines, Intel macOS 12, and ARM macOS 15, and with both the Apple provided bash and zsh shells.

This could just be poor default settings on macOS?
