video: (shows v.1.1)

commands available:

(all shortcut keys may be changed in the UE4 Editor settings)


Edit the comment text

Simply select the command node, hit the E key, and start editing.

(for pre v1.2 behavior, pls. change key assignment in UE editor settings)


Hide / unhide the comment text

toggle: If at least one comment of the selected nodes is visible, hide them.

If none of the selected is visible, unhide non-empty comments again.

P / U:

Pin or unpin the bubble zoom

To control whether the bubble should zoom with the graph, or stay at a readable 1:1 size


Clear the comment

Delete the comment text and hide the comment bubble.

Does not delete text from hidden comments.


Pin & Edit the comment text

like Edit, but also pins the zoom size. Useful to edit when heavily zoomed out


Fill the comment bubble with the node title and pin the size.

Useful for event nodes to still find them while zoomed out.

ALT-E only fills nodes of type 'event', but doesn't touch 'normal' nodes, even if selected.

Useful to only fill several event nodes, without having to avoid the 'normal' nodes when selecting.

CTRL-ALT-E fills all types of nodes.

Both commands don't touch nodes which already contain a comment.


Use the standard CTRL-Z undo command
