DYN-9637 - Add keyboard shortcuts to quickly navigate the canvas to the leftmost (“beginning”) and rightmost (“end”) nodes of the active graph.

[CustomBuildingConfigurators-Balaji]

Purpose

Add keyboard shortcuts to quickly navigate the canvas to the leftmost
(“beginning”) and rightmost (“end”) nodes of the active graph. (DYN-9637) -

New shortcuts:

• Home: navigate to the beginning (leftmost node position).
• End: navigate to the end (rightmost node position).

Definitions:

• Consider only visible, placeable nodes (ignore Notes/Annotations/Groups by default).
• Beginning = nodes with minimum X (left edge of node bounding box). End = maximum X (right edge).
• If multiple nodes share the same extreme within a tolerance (e.g., ±2 px), zoom/pan to show all of them.

Behavior:

• Smooth pan/zoom animation (150–250 ms).
• If no nodes exist in workspace, no action. o If leftmost or rightmost node is inside a Collapsed Group, Zoom to the group to show the full group in view.
• Respect editing context: shortcuts are handled only when canvas is focused and no in-place text editing is active (e.g., Code Block editor, rename fields).

Declarations

Release Notes

New shortcuts:

• Home: navigate to the beginning (leftmost node position) when there is no active selection in workspace.
• End: navigate to the end (rightmost node position) when there is no active selection in workspace.

Pull request overview

This PR adds keyboard shortcuts to navigate the canvas to the leftmost (Home key) and rightmost (End key) nodes in the active graph, addressing feature request DYN-9637.

Changes:

• Adds Home and End key bindings to the DynamoView XAML that trigger navigation commands
• Implements GotoLeftMostNode and GotoRightMostNode commands with corresponding CanExecute methods
• Uses a 2px tolerance to group nearby nodes at the extremes and includes their containing groups in the navigation

One bit of feedback from someone testing:

Doesn't zoom to notes or groups with only notes in them.

So in a graph if you have notes at the beginning or the end, it is only considering NodeModels at this time.

Hi @johnpierson ,
The requirement was to consider only nodes and groups. Kindly refer the first point in the Definition section and second point in the Behavior section of this PR.
Thanks.
