# Termianl Emulators
# Terminal Emulators
I used to spend a lot of time on terminal emulators, to make them match my taste,
but now I found that it's not worth it, **Zellij can provide a user-friendly and unified user experience for all terminal emulators! without any pain**!

My current terminal emulators are:
1. kitty: My main terminal emulator.
1. to select/copy a large mount of text, We should do some tricks via kitty's `scrollback_pager` with neovim, it's really painful: <https://github.com/kovidgoyal/kitty/issues/719>

2. wezterm: My secondary terminal emulator.
1. its search ability is very basic, and it's not easy to use.
1. its scrollback buffer's copy mode is very like vim, which is nice, but zellij's even better, it can use neovim as its default scrollback buffer's editor without any pain!

3. foot: a fast, lightweight and minimalistic Wayland terminal emulator.
1. foot only do the things a terminal emulator should do, no more, no less.
1. It's really suitable for tiling window manager or zellij users!

### Solutions
Simplest solution, it will automatically copy over the terminfo files and also magically enable shell integration on the remote machine:
