st is the suckless terminal emulator.

Luke's collection of patches at https://github.com/LukeSmithxyz/st provide some additional functionality and keybinds. Some integration with dmenu is also useful.

• scrollback with alt-↑/↓ or alt-pageup/down or shift while scrolling the mouse.
• OR vim-bindings: scroll up/down in history with alt-k and alt-j. Faster with alt-u/alt-d.
• zoom/change font size: same bindings as above, but holding down shift as well. alt-home returns to default
• copy text with alt-c, paste is alt-v or shift-insert

• st from the ground up with needed patches
  • scrollback
  • externalpipe
  • lukesmith custom stuff (selection, follow links)

You can copy text over SSH via OSC-52 escape code. st supports this and can be enabled with int allowwindowops = 1; in your config.
