I'm in the process of updating lazygit to use tcell v2.13.4 (not v3 yet, this will come next).

There's a regression with handling ctrl-J on macOS Terminal (version 2.14, I'm on macOS 15.7.3) and on VS Code's built-in terminal: pressing ctrl-J gets reported as KeyCR, not KeyCtrlJ as it used to. My suspicion is that these don't support the CSI-u protocol, but I haven't verified that.

Other terminals report it correctly as KeyCtrlJ (ghostty, WezTerm, iTerm2).

That's a show-stopper for adoption of the new version for us, as ctrl-J is a frequently used keybinding in lazygit.

EDIT: tested it with v3 too now (v3.0.3), same problem there.
