There are a number of existing issues about having keymap conflicts and/or being able to remap individual keymaps in claude code that cause conflicts or don't conform to user's expectations.

The new issue I ran into was the new ctrl+g for external text editor conflicts with Zellij's lock mode

This is an overarching issue requesting the ability to remap all keymaps as there is such a wide variety of shortcuts people need to be able to remap.

Proposed Solution

Allow for remapping of all keymaps.
