How to select all the images on the left (or right) in Lightroom filmstrip? i.e similar to Ctrl+Shift+Home or Ctrl+Shift+End in text editors

How do I select all the images on the left (or on the right) in a Lightroom filmstrip? i.e similar to Ctrl+Shift+Home or Ctrl+Shift+End in text editors.
There seems to be no way and I have to use shift with left/right arrows to do the selection which is a cumbersome process if you have hundreds of photos
