You can select multiple annotations by using the annotation selection tools
instead of using the 'Select' tool in the radial menu, you can use the
'Line' select tool, allowing you to draw a line through each selection
that you'd like to select.
- Select the arrow next to the 'Pan' option in the radial menu. This will open the select submenu.
- Select the 'Select' icon from the selection submenu.
- Select the desired annotations (left mouse/touch/stylus and drag to select annotations within the bounding box).
