Kitty is the best one. It has several features which have proven so useful I wasn't able to stay on anything else for more than a couple of hours (including the one this topic is about).

Ctrl+Shift+G wraps the output of the previous command into a pager (say, less). You often only know you needed a pager after that output is printed.

Ctrl+Shift+E highlights all links on the current screen and assigns short alphanumeric codes to them, so you can open links without using the mouse. For example, `Ctrl+Shift+E 1` opens the first link, `.. 2` the second one, etc.

Ctrl+Shift+U opens symbol search where you can find & insert symbols using their unicode names. Emoji, TUI blocks, rare accented characters you need once in a blue moon, CJK ideographs, whatever.
