How to move layers in illustrator using keyboard, for sub layers we had option to move it.

I am selling an action for Keyboard Maestro to do that. An environment in which Keyboard Maestro can be used is required.

Action for Keyboard Maestro that moves the selected layer around the panel

If you want to solve this problem by yourself, create many scripts like the following and assign shortcuts to them.

app.activeDocument.activeLayer.zOrder(ZOrderMethod.SENDTOBACK) ;

Unfortunately, I can't give you any shortcuts. If I want to move something, I do it in the layers panel by drag&drop. Or by script for multiple files.

I rarely use actions. But maybe @Kurt Gold can help you with that.

On the other hand - when a new layer is created with a script, it is always at the top. Here is the [JS] code for it.

var aDoc = app.activeDocument;
aDoc.layers.add();

Manually selecting and dragging them to change the z-order is not what you are looking for, isn't it?

It has to be asked because your request is quite silent.

In layer panel itself I want to move it up and down.
