Keybindings & About

The Keybindings section rebinds every action; conflicts are resolved for you and shown inline. About lists the version, license, and links to the repository. See Shortcuts for the default keymap.

Preferences are written to config.toml in bloom's config directory:

  • Windows: %APPDATA%\bloom\config.toml
  • macOS: ~/Library/Application Support/bloom/config.toml
  • Linux: ~/.config/bloom/config.toml

You can edit it directly; unknown or out-of-range values fall back to their defaults. Some rendering options note "restart required".
