Is it possible to group action without having an undo related .... ?

Question

im writing a CEP panel extension and trying to sync a sourceText keyPoint with a text marker.

When the user changes the text marker I move the sourceText keyPoint so it stays aligned

The problem is doing so generates a lot of undo history.

Is it possible to group actions without having an undo generated ?

Or is there a better way to align a keyPoint sourceText with the value of a text marker?

thanks

Mat

I want to hide the undo group. Not create it.

let say I do this

var stProps = layer.property("sourceText");

stProps.setValueAtTime(startTime, new TextDocument(startTxt));

stProps.setValueAtTime(endTime, new TextDocument(endTxt));

but I don't want to have this in an undo nor in a group.

I have a polling mechanism running a script every 500 ms

and don't want to have undo action based on what's happening in that script.

Gotcha, pass an empty string into the undo group, and it will be hidden from the undo history:

app.beginUndoGroup('');
// your code
app.endUndoGroup();

Use Undo Groups to group all your actions into one undo:

app.beginUndoGroup("My Function");
// your code
app.endUndoGroup();
