Commands define actions that SilverBullet can perform. They range from simple edit commands, such as Text: Bold, but may be more elaborate such as Page: Rename.
SilverBullet ships with a lot of commands built in, but custom ones can also be defined using [Space Lua](Space Lua) and Plugs.
All commands available commands appear in the [Command Palette](Command Palette) but may have key bindings as well (these key bindings appear in the [Command Palette](Command Palette) and are configurable in [Configuration Manager](Configuration Manager)).
You can create custom command using the ^Library/Std/APIs/Command API.
