kitty is a cross-platform, fast, feature full, GPU based terminal emulator.

It is designed for power keyboard users. To that end all its controls work
with the keyboard (although it fully supports mouse interactions as well).
Its configuration is a simple, human editable, single file for easy
reproducibility (I like to store configuration in source control).

Finally, kitty is designed from the ground up to support all modern terminal
features, such as unicode, true color, bold/italic fonts, text formatting,
etc. It even extends existing text formatting escape codes, to add support
for features not available elsewhere, such as colored and styled (curly)
underlines. One of the design goals of kitty is to be easily extensible so
that new features can be added in the future with relatively little effort.
