Keyboard Commands, Selection

• I am trying to figure out how to click on a link in the content/notes pane and add it to the selection list.

I used to be able to select an entire column in a table and add it to the selection list with one keyboard command.

I should be able to hold Shift + click on the links below to add to the selection list. Instead I have to click on each one at a time and then link to parent or child or jump and then switch back to here and do the next one at a time. What's the purpose of a Selection List if it's not accessible?
