Config file

Open Settings (Cmd , / Ctrl ,) or edit the file directly. Each line is key = value. Comments start with #.

theme = termy
font_family = JetBrains Mono
font_size = 14
shell = /opt/homebrew/bin/fish
keybind = cmd-p=toggle_command_palette

Termy does not bundle custom fonts. A font_family value must name a family installed on your system; if it is missing or not fixed-pitch, Termy shows a warning and falls back to the platform monospace default (Consolas on Windows, Menlo on macOS). On Windows, if an installed font is still not found, try reinstalling it for all users rather than only your account.

Colors

Only [colors] uses a section header:

[colors]
foreground = #e7ebf5
background = #0b1020
