Describe the bug

Environment:

• Windows
• Using wsl inside Warp.

Description:

I have a program that I run and I bind it to CTRL+r (overriding the default bash CTRL+r). It works, but in Warp CTRL+r is already overritten by a Warp feature.

So, in Warp config I changed the Warp's CTRL+r to something else, and bing my own using:

bind -x '"\C-r": "source /usr/local/bin/my_own_command"'

Now when I press CTRL+r, the letter "r" appears on prompt, ignoring completely the CTRL.

I tried to set the binding in .bashrc and reestart Warp, but nothing works.

Can't bind other keys in Warp using the bind command.

To reproduce

• Change the Warp default binding CTRL+r to something else.
• Run bind -x '"\C-r": "ls /"' to run ls / when pressing CTRL+r.
• Press CTRL+r

Expected behavior

List the files and directories in /.
