Manjaro i3: what’s a good terminal alternative to urxvt that is similarly lightweight/keyboard-focused but more configurable at run-time

Personally I like kitty allot good customization options (including keymapping for instance) and easy to use imo.

Almost forgot.
It also plays very nice with Ranger. For (in terminal) image preview for instance all you need is pillow and set preview_images_method kitty in your rc.conf
