Manually align specimens to annotated 3D spaces

Keyboard Accelerators and Mouse Operations

On macOS use the Command key (⌘) instead of the Control (Ctrl) key

General

Key	Effect
Ctrl + n	Create a new annotation
Ctrl + s	Save current annotation
Ctrl + o	Load an annotation from file
Ctrl + w	Reset views discarding current changes

If it applies, user will be prompted with a save dialog before creating, saving or loading a annotation.

2D Viewer

Key	Effect
f	Increment Slice offset
b	Decrement Slice offset
r	Adjust field of view to match the extent of the atlas

Zoom and Pan (available in Exploration and Edit mode)

Interface Device	Zoom	Pan
3-button mouse	Right-Click & vertical drag	Middle-Click & drag
2-button mouse	Right-Click & vertical drag	Shift+Left-Click & drag
1-button mouse	Ctrl+Left-Click & vertical drag	Shift+Left-Click & drag
Trackpad	two-fingers & vertical drag	Shift+Left-Click & drag

Annotation (available in Edit mode)

Key or mouse operation	Effect
Left-Click	Add annotation point
Delete	Delete currently selected annotation point
Ctrl + Left-Click on annotation line	Insert annotation point
Left-Click near annotation line & drag	Translate annotation
Right-Click near annotation line & drag	Scale annotation

3D Viewer

Key	Effect
f	Increment Slice offset
b	Decrement Slice offset
r	Adjust field of view to match the extent of the atlas

SpinBoxes and Sliders

• Right/Left key: SingleStep increment
• PageUp/PageDown key: PageStep increment

	SingleStep increment	PageStep increment
Raw/Pitch/Yaw	1	5
Annotation Thickness	1	10
Slice Step Size	1	10
Slice Offset	<slice step size>	<slice step size> * 10

Known Issues

• Inserting point in a Spline annotation does not work reliably. Workaround by switch the annotation type to PolyLine and then inserting the point. See #80
• For Roll, pitch and yaw, the angle mappings differ from the coordinate system the lab uses. See #81
• After using Ctrl+w and restarting the application, mm unit prefix is displayed instead of um. See #89
