Note: this page is work in progress.

Application Hot-keys (keyboard accelerators)

  • Alt-Left + mouse button should always be available as a substitute for the middle mouse button to support two button mice. On Mac, you can also use the command key + mouse click to get middle mouse events.
  • Control-Left + mouse button should always be available as a substitute for the right mouse button to support one button mice (on Mac).

Warning Warning: Developers: Please note the following reserved key combinations!

General

Key(s) Action bound to key(s)
Ctrl+O Load a new scene (clears existing scene)
Ctrl+A Import a scene (does not clear existing scene) Brings up Add Data instead
Ctrl+W Close a scene
Ctrl+H Set the current module to be the "home" module -- the module that's exposed when Slicer starts up.
Ctrl+Z Undo the last undoable action
Ctrl+Y Redo the last lightpinkoable action
Space-key Toggles the display of Slicer's Edit Box.
Ctrl+P Display the Python console Displays the QT-real console
Ctrl+L Create a new fiducial list.
Ctrl+I Toggle between "Persistent Place" and "Transform View" interaction modes.
Ctrl+M Create a new Ruler measurement between the last two placed fiducials.

Slice Viewer Hot-keys (keyboard accelerators)

Key(s) Action bound to key(s)
` (back-tick key) Navigate to next fiducial in the active Slice Viewer, or in all viewers if they are linked (back-tick is the left single-quote on the key with the tilde (~) character in the upper left side of the keyboard)
Ctrl+` (back-tick key) Navigate to next fiducial in all Slice Viewers, independent of their linked state
Shift+` (back-tick key) Navigate to the previous fiducial in the active Slice Viewer, or in all viewers if they are linked
Ctrl+Shift+` (back-tick key) Navigate to the previous fiducial in all Slice Viewers, independent of their linked state
p-key Place a new fiducial in the active Slice Viewer(adds to the current fiducial list, or creates a list if there are none)
o-key Turn on the Slice Plane reformat widget in the active Slice Viewer
v-key Toggles the slice plane visibility in the main 3D Viewer
r-key Fits the slice view to the volume extents in the active Slice Viewer, or in all viewers if they are linked (the first non-none volume will be used in order of Background, Foreground and Label layers)
b-key Decrement slice in the active Slice Viewer (left or down) by one unit of background pixel spacing
f-key Increment slice in the active Slice Viewer (right or up) by one unit of backgroun dpixel spacing
Backspace-key When the mouse is hovering over a fiducial in the Slice Viewer (turning it yellow), delete that fiducial
Delete-key When the mouse is hovering over a fiducial in the Slice Viewer (turning it yellow), delete that fiducial

Sliders and mouse

  • Every click is 1 step, and 1 step is 1 slice (if there are multiple volumes (Labelmap/Back/Foreground, then its the smallest spacing of the 3 that is used).
  • Middle click directly jumps to the mouse.
  • Home/End keys go to the beginning/end.
