Ganimede provides keyboard shortcuts for common operations. Since Ganimede uses a canvas-based interface, most shortcuts work when you have focus in a code editor or when interacting with cells.

​
Code Editing

​
Run Cell

​
Cmd+Enter / Ctrl+Enter
shortcut
Execute the current code cell. This queues the cell for execution if it’s in an idle state.
When you press Cmd+Enter (Mac) or Ctrl+Enter (Windows/Linux) in the Monaco editor:
  • The cell is added to the execution queue
  • Only works if the cell is in idle state
  • The kernel will execute the cell and display outputs

​
Document Operations

​
Undo

​
Cmd+Z / Ctrl+Z
shortcut
Undo the last change to cell structure (not code content).
The undo manager tracks:
  • Cell creation and deletion
  • Cell movement and reorganization
  • Changes to cell hierarchy
Note: Code content changes within Monaco editor use Monaco’s built-in undo (also Cmd+Z / Ctrl+Z).

​
Canvas Navigation

​
Pan Canvas

​
Click + Drag
mouse
Click and drag on the canvas background to pan around your notebook.

​
Zoom

​
Scroll Wheel
mouse
Use the scroll wheel to zoom in and out of the canvas. Hold Cmd/Ctrl while scrolling for more precise control.

​
2D Scrolling

​
Scroll / Trackpad
mouse
The canvas supports 2D scrolling - use your trackpad or scroll wheel to move in any direction.

​
Cell Operations

​
Create New Cell

​
Right Click
mouse
Right-click on the canvas to open the context menu with options to create:
  • Code Cell (Python)
  • Text Cell (Markdown)

​
Drag Cell

​
Click + Drag on Cell Toolbar
mouse
Click and drag the cell toolbar (top bar of any cell) to move the cell around the canvas or reorganize cell hierarchy.
When dragging a cell:
  • Orange border indicators show where the cell will be placed
  • Drop on another cell to create a parent-child relationship
  • Drop on empty canvas to make it a top-level cell

​
Collapse/Expand Cell

​
Click Collapse Buttons
mouse
Hover over a code cell to reveal collapse buttons on the left:
  • Click the top button to collapse/expand the input (code)
  • Click the bottom button to collapse/expand the output
Collapse states:
  • i: Input collapsed only
  • o: Output collapsed only
  • b: Both collapsed
  • null: Both expanded

​
