## Changing the length and position of labels with the mouse

### Point label

- You can move a point label by clicking and dragging its circle handle.
- You can turn a point label into a region label by clicking and dragging either of its chevron handles.

| You can also move a point label by holding the Shift key down while clicking and dragging the circle or either of its chevron handles. Using this shift-modified click&drag with a point label avoids any risk of accidentally creating a region label.

### Region label

- You can change the length of a region label by clicking and dragging its circle or either of its chevron handles.
- You can move a region label by dragging the central line of it, or by holding the Shift key while clicking and dragging its circle or either of its chevron handles.
- In the case where two region labels meet you can adjust the junction point where they meet by clicking and dragging their shared circle handle.

## Moving a point label

You can move a point label by clicking and dragging its circle handle:

  Before | After

| You can also move a point label by holding the Shift key down while clicking and dragging the circle or either of its chevron handles. This avoids any risk of accidentally creating a region label.

### Take care when moving point labels

Be very careful when moving a point label not to accidentally click on a chevron and thereby expand the point label to a very short region label.

This can cause unwanted consequences when using Export Multiple, exporting a short audio file based on the short region label.

There is a slight visual cue to distinguish between a point label and a region label too short to display at the current zoom level.

The region in the label track never collapses down to a single line, rather there is always a line for each edge of the region resulting in a double line, slightly visibly thicker:

| With a compacted region label like this if you click on the circle the label will collapse to a point label.

## Expanding a point label

You can expand a point label into a region label by clicking and dragging either of its chevron handles:

  Before | After

## Resizing and moving a region label

### Resizing

You can change the length of a region label by clicking and dragging its circle or either of its chevron handles:

  Before | After

### Moving

You can move a region label by clicking and dragging its central bar:

  Before | After

## Adjusting the junction point where two labels meet

You can adjust the junction point where two labels meet by clicking and dragging their shared circle handle:

  Before | After

## Moving a label when there is a selection

The illustration below shows what happens if you click in a label to select it, press Enter, then move the label.

  Before moving a label with a selection | After moving a label with a selection

Contrast this to what happens if you click in a label to select it, then move the label.

## Using cut, copy and paste

The following examples of cutting labels with Edit > Cut will move back any labels that follow to right of the removed label(s). To cut the label without moving following labels, use Edit > Remove Special > Split Cut.

### Cutting and Pasting Region Labels

You can cut and paste region labels using Edit > Cut and Edit > Paste, but you have to make sure you do not select any audio, or you will end up cutting and pasting audio where you probably did not intend.

In the image below, the label was selected by clicking in it, then the audio track was unselected by Ctrl-clicking in the Track Control Panel's Select button of the audio track (this can also be done with the keyboard by Enter, Up then Enter).

The label was then cut to the clipboard with Edit > Cut:

To paste the label at a different point in the audio track, either

- click in the label track at the point where you would like the label to begin, or
- click in the audio track at the point where you would like the label to begin then Shift + Down-arrow to extend the selection to the label track.

The label can then be pasted to that spot using Edit > Paste.

### Cutting and Pasting Point Labels

To cut and paste a point label to a different location, first select the text of the label as shown below. Note the difference in appearance of selected label text (the text is highlighted separately from the box) versus a selected label (where the entire label box is highlighted).

1. Do Edit > Cut (shortcut Ctrl + X) - the text of the label is cut to the clipboard, leaving a label with no text.
2. Press Delete to delete the label, or right-click in the label and choose Delete Label from the context menu.
3. Click in the new location for the label and do Edit > Labels > Paste Text to New Label.

## Using the Context Menu

If you right-click on a label, the label's context menu will appear:

The context menu offers the following options

- Cut: - cuts any selected text in the label and place it on the clipboard
- Copy: - copies any selected text in the label and place it on the clipboard
- Paste: - pastes the contents of the clipboard to the label
- Delete Label: - deletes the entire label
- Edit: - opens the Labels Editor with just the current label

## Using the Labels Editor

The Labels Editor lets you add or remove Label Tracks and edit their labels entirely using the keyboard, so is particularly useful for visually impaired users.

Edit > Labels > Edit Labels... launches a keyboard-accessible Labels Editor. This shows all the labels at once in a tabular view, similar to a spreadsheet. Each row represents a single individual label:
