# The Sequencer Grid

The sequencer grid is the heart of Cagire. Each cell represents a step that can contain a Forth script to generate sound.

## Structure

- **Steps**: Up to 128 per pattern, displayed 32 at a time
- **Patterns**: Up to 32 per bank
- **Banks**: Up to 32 per project

## Navigation

Use arrow keys to move between steps. The grid wraps around at pattern boundaries.

## Selection

Hold `Shift` while pressing arrow keys to select multiple steps. Press `Esc` to clear the selection.

## Editing Steps

- `Enter` - Open the script editor
- `t` - Toggle step active/inactive
