Deleting photos from Lightroom from a mackbook

[Guest]

Hi, all. I am using Lightroom on a MacBook Pro 2019, I am trying to figure out how to delete multiple photos from  Lightroom. Any help would be greatly appreciated. I can only seem to delete one photo at a time and with over 7000 photos , that is exhausting. Thank you all in advance.

Select multiple photos selectively while holding Ctrl/opt key.

Select a sequence of photos by selecting the first, then hold the Shift key and select the last.
