How to load samples? (I'm using Reaper on Windows)

Can’t drag samples into it (it just adds the file as a separate track). There is no button in the UI to select a sample. I’m using Reaper on Windows.

Not off to a good start.

Support replied. The answer is you have to hit the little arrows in the sample area. For a reason I cannot fathom, someone said “Hey let’s take the most important action, like the thing you have to do first before you can even use the thing, and let’s make it a tiny icon in the corner”.

Memorizing manuals and exploring aimlessly is not a solution to a user interface problem. FYI On page 11 is a completely different feature: that’s for importing presets. For importing samples, that’s on page 16 and there is no screenshot of that. My issue has already been resolved.
