Creating, Editing and Deleting Annotations
The left side bar of the annotation tool will display the Taxonomy you created. There are three sections to the side bar (that will be present depending on your taxonomy) - Study Classification, Series Classification and Object Labels.

If present, the study and series classifications will be present under their own expansion panels. You will be able to directly fill out the checkbox, select, or textfield in the grid.

An object label has three components - a category name, a label type, and attributes (optional). The left side bar will show all the object labels on the left side bar with an option to create instances of that object label. All instances are organized within each object labels expansion panel.
Simply click the (+) button of the object label you want to create. Doing so will create an instance of that object label, and automatically select the default tool for that label type ex. for segmentations, the brush tool will be selected by default.
Use the number shortcuts i.e. 1, 2, 3, etc., to quickly create object labels

To edit an object label, you must first select it from the left sidebar. Once you select the instance from the left side bar, the default tool for that label type will be selected and you can interact with the canvas to make edits to that instance.
When a object label instance is selected, interacting with the canvas will only edit that particular instance.
There are several actions available that can help you with selecting, viewing, and editing object labels. All actions can be accessed by clicking the three dot menu button on a label instnance.
You can edit the selected labels attribute and category on the right side context panel. Either select the label, or click on the "Edit" label action to display the right side context panel.

You can delete the selected object label by using the
delete / backspace shortcut. Alternatively, you can use the delete action in the actions dropdown. To delete all labels use the shortcut
shift + delete/shift + backspace. Alternatively, you can use the delete all action in the Object Labels three dot menu dropdown. You can hide the label you are currently hovering over by using the
h hotkey. If you are not hovering over any label (either on the canvas, or on the left side bar), the h hotkey will hide/show the currently selected label. To hide/show all labels use the shortcut
shift + h or the hide all action in the Object Labels three dot menu dropdown. You can lock/unlock label you are currently hovering over by using the
u hotkey. If you are not hovering over any label (either on the canvas, or on the left side bar), the u hotkey will lock/unlock the currently selected label.To lock/unlock all labels use the shortcut
shift + u or the lock all action in the Object Labels three dot menu dropdown. Watch the video below to understand how to prevent/allow overwriting of annotations.
Vibrant mode allows you to temporarily highlight a particular instance. For example, if you have several small instances of nodules in a chest CT, you can hover over any particular instance on the left side bar or on the canvas, and use the
v shortcut to activate vibrant mode to highlight that instance. This can be useful in quickly identifying instances. The Jump to label action will change the current slice position to the closest slice position that contains a particular annotation. This is useful for revealing annotations on the canvas.
