I don’t know what the standard C-p and C-n bindings are. Could you share?

The startup time is a known issue and scales badly with extensions. We’re aware of it but fixing it is tricky.

C-p and C-n (aka Ctrl-P and Ctrl-N) are the Emacs-style keybindings for previous (line) and next (line), very commonly encountered on the command line and in terminal applications. For example, most shells can use this in addition to up-arrow and down-arrow to cycle thru command history. Many, many more examples exist of applications (not just terminal-based, there are plenty of GUI apps too) that use this convention, as well as other Emacs-style keybindings (e.g. C-a for beginning of line, C-e for end of line).

Ctrl+P in most coding agents is bound to bringing up a command bar. You should be able to bind both hotkeys to the functionality you want already.

Naturally! Being able to use your tools how you want/what works best for you is fundamental in my opinion.

That's wrong. Both Claude Code and Codex have C-p/C-n as down/up.
