Keyboard-first todo app

Capture the thought before the shortcut leaves your fingers.

Argon is built around selection, search and creation from the keyboard. The core shortcuts are remappable, and an optional Vim mode adds home-row navigation and two-key commands.

Optional Vim mode

Actions

Two-stroke commands wait for the second key, and esc cancels a sequence part-way through.

Remapping

Core commands

Quick Add, Quick Find, create, edit and delete each have selectable alternatives in Settings.

Vim commands

Every Vim action can be changed, including the two-stroke commands, or individually turned off.

Safe text entry

Plain-key shortcuts are ignored while you are typing into editable fields, so navigation does not eat your notes.

A practical loop

Capture outside Argon

  1. Press ⌘⇧Space from wherever you are.
  2. Type the todo while the thought is still fresh.
  3. Press ↵ and carry on with what you were doing.

Process inside Argon

  1. Press ⌘F to jump to a view, section or todo.
  2. Use the arrow keys, or j and k in Vim mode, to select work.
  3. Press ↵ to edit, or x in Vim mode to complete.
