+# order list
+
+the order list is a playlist for patterns.
+
+![order list](order-list.png)
+
+along the top are the available channels. their abbreviations can be set in the [channels window](../8-advanced/channels.md). the highlighted channel follows the channel the pattern view cursor is in.
+
+along the left are the order numbers. these are referenced with the `0Bxx` command. the highlighted row follows the order the pattern view cursor is in.
+
+each entry in the table is the pattern that will play during that order. these can be changed according to the order edit mode.
+
+hovering over a pattern number will pop up a tooltip showing the name of that pattern, if it has one.
+
+The buttons are as follows:
+- **Add new order**.
+- **Remove order**.
+- **Duplicate order**: adds a new order with patterns matching the selected one directly below it. right-click to "deep clone"; this copies all patterns involved to new ones.
+- **Move order up**: swaps the selected order with the one above it.
+- **Move order down**: swaps the selected order with the one below it.
+- **Duplicate order at end of song**: same as "Duplicate order" except the new order is added at the bottom of the list.
+- **Order change mode**: selects how much of the order will change with an edit. only applies if "Order edit mode" is set to "Click to change".
+  - **one**: only current channel's pattern will change.
+  - **entire row**: all patterns in the order will change.
+- **Order edit mode**: selects the method of changing orders.
+  - **Click to change**: a click will add one to the pattern number. a right-click will subtract one.
+  - **Select and type (don't scroll)**: select a pattern and type.
+  - **Select and type (scroll horizontally)**: as above, but after entering two digits, the cursor moves to the next channel.
+  - **Select and type (scroll vertically)**: as above, but after entering two digits, the cursor moves to the next order.

+input latch determines which data are placed along with a note. as in the pattern view, the columns are note (not changeable), instrument, volume, effect type, and effect value.
+- `&&` fills in the currently selected instrument.
+- `..` ignores the column.
+- all columns (except note) can be reset with a right-click.
+- **Set**: sets latch according to the data found at the cursor.
+- **Reset**: resets all columns to default (selected instrument, ignore others).
+- only the first effect type and effect value may be latched.

+the operation mask toggles which columns will be affected by the listed commands. as in the pattern view, the columns are note, instrument, volume, effect types, and effect values. the effect toggles apply to all effect columns.
+
+click any area to toggle it. a `---` or `--` means the listed command will ignore any data in that column.
