Hello, I am placing many markup points on a surface in the 3D view. Occasionally I middle-mouse drag to pan the 3D view and I accidentally end up dragging all the control points for the node. This operation is not undo-able as far as I can tell. Is there any way to disable middle-mouse drag for mar…

There are two ways to mitigate this problem. Either per point basis or for all points in the markup object. After placing the markup point in correct position, you can click the lock button next to it in the control points table. You won’t be able to reposition this landmark until you unlock it. …

If you find yourself doing this a lot, you could assign a keyboard shortcut that locks/unlocks the current node. This thread should help: Undo feature for Markups module · Issue #4576 · Slicer/Slicer · GitHub

@muratmaga Thanks for the insight. I have over a thousand points and I need to leave them unlocked for editing, but I discovered that if even a single control point is locked, then middle-mouse dragging of all control points is disabled.

@muratmaga I do believe that left-click to drag a single point and middle-click to drag all points within a node is the intended behavior (I’m on Slicer v5.3.0). The idea of assigning a shortcut to lock / unlock the node every time I want to pan in the 3D view is reasonable solution, but In my case…

[image] JASON: I do believe that left-click to drag a single point and middle-click to drag all points within a node is the intended behavior (I’m on Slicer v5.3.0). No from my perspective that’s a bug, and a costly one, as you cannot undo it! I am surprised it is not fixed. The same function…

Definition of a bug: a feature that cannot be turned off. This feature can be turned off by mapping the middle-button click-and-drag interaction event to no widget event. It requires Python scripting, so you may argue that it cannot be turned off. Maybe we should make these event mappings adjustabl…

[image] lassoan: Alternatively, you can enable undo/redo for markups. That would be the most useful thing. How do you do that?
