Commands

Commands

Every command nem has, by name. M-x runs any of them by name, with fuzzy completion: M-x fwc finds forward-char. nem.bind binds a key to any of them, and nem.run runs one from a command of your own. Commands you define with nem.command join this list, as equals.

A key in a mode - dired: f - works only in that mode's buffers; see Keybindings.
