[Query] Any way to make existing Emacs keybindings work with X windows in line mode?

[khalidrafi6]

I use evil and I have some keybindings like j for down, e for up. Line mode ignores them. But, is there any way to make keybindings that are valid X window input to be sent automatically? If not, how can I get these keybindings to work in line mode with X windows?

You have to configure simulation keys. However, if you configure j and e to mean "up" and "down", you're going to have difficulty typing those keys.

I've seen some packages that try to support modal EXWM input (e.g., https://github.com/walseb/exwm-firefox-evil) but I have no experience with them.
