Keyboard Mappings

The problem with keyboard input on terminals are described here, which can be fixed with keyboard mappings, e.g.:

[keyboard]

bindings = [
  { key = "I", mods = "Control", chars = "\u001b[105;5u" },
  { key = "Tab", mods = "Control", chars = "\u001b[9;5u" },
  { key = "Tab", mods = "Control | Shift", chars = "\u001b[9;6u" },
  # ...
]

showkey -a can be very useful to find the keycode and verify the mappings.

Display Emoji

Install Noto Color Emoji and then add following content to $XDG_CONFIG_HOME/fontconfig/fonts.conf¹:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
  <alias>
   <family>sans-serif</family>
   <prefer>
     <family>Noto Color Emoji</family>
