Can't access sub-tools ( SOLVED )

On some of the tools in the tool shelf, there are additional options, which are accessed by clicking on a little arrow in the lower right of the tool icon. For example on the annotate tool, some of the sculpt tools, etc. When I click on the little arrow, nothing happens. Is anyone familiar with this behavior and how to fix it? Thanks for any help.

I figured it out. It’s L click + drag. I was missing the drag part.
