Default Thumbnail Size

I have a button that changes the view to Thumbnails but it always defaults the thumbnail size (slider) to 128. I want it to default to 256 but there is no argument in Set VIEW=Thumbnails for the size.

You can set the default thumbnail size under Preferences / File Display Modes / Thumbnails if you want it all the time.

If you only want it when using one particular button, add the command Show THUMBNAILSIZE=256

Thanks, that worked.
