I like using tilde, as it’s very similar to MS-DOS EDIT.COM style text editors
If I need something more advanced I can always call a different editor but this one’s nice, with the familiar File / Edit / View menu bar and standard keyboard shortcuts.

EDIT: Seems I got it installed and working using the following (CentOS 8 repo on author’s website):
curl -fsSL https://download.opensuse.org/repositories/home:/gphalkes:/tilde/CentOS_8/home:gphalkes:tilde.repo | sudo pkexec tee /etc/yum.repos.d/tilde.repo
sudo dnf install tilde
NB: Three of the default Menu keys (Alt+F, S, and O, which open File, Search, and Options) are by default bound to the terminal manager. To access those menus, hit Shift+Alt+F, S, or O.
