Ctrl+PageUp in 9.2.0204

[jazztickets]

I'm using ctrl+PageUp/ctrl+PageDown to switch between tabs but after upgrading to vim 9.2.0204 in Arch Linux, ctrl+PageUp no longer goes to the previous tab. Instead it's sending ctrl+e and scrolling one line down. Tested with xfce4-terminal and gnome's terminal. Do I need to change something in the terminal?

[Gary Johnson]

I can verify this on Ubuntu 24.04.4. I did a git bisect and found
the difference (bug?) to have been introduced at patch 9.2.0192.
This behavior is not affected by "k" in 'cpoptions'. I haven't
looked into it further.

patch 9.2.0192: not correctly recognizing raw key codes

Problem: When "k" is excluded from cpoptions, vim should be able to
recognize raw key codes in mappings and replace them with
builtin codes (e.g. ^[OA is replaced with <Up>) so that
changing the builtin code also changes the mapping to match.
Currently, this only works properly if the builtin code does
not contain modifiers (e.g. @;*).
Solution: Teach find_term_bykeys how to recognize keys with modifiers
(AstroSnail).

I forgot to mention that the terminal I used was xterm version 403
and the desktop environment was GNOME 46.0.

However, I discovered that the issue is not present in the latest
Vim, 9.2.209, when using GNOME Terminal version 3.52.0.

Thanks for reporting, but it's not clear to me is this issue only
present in xterm? Or is it resolved with latest master?

Thanks,
Christian

For me the issue is still happening in 9.2.209 on the terminals I've
tried: xterm,
xfce, gnome console, gnome terminal. It is working however on Konsole, which
also worked in 9.2.204.
