Rate Calendar: what do these options do?

I am using the Rate Calendar to set some spot rates and I notice on the right hand corner of the calendar these options:

Toggle
Range
Columns

If I click on any of them, nothing happens.

I'm curious what the purpose of these options are?

I've read the "Spot Rates" article below, but it does not mention these options.

Does anyone know?

Those are different selection modes for the calendar.

With Toggle, you pick one day at a time and clicking adds or removes to your selection.

Range is click and drag to select. You can also Ctrl+Click new ranges to add to your selection.

Columns is click and drag to select like Range but it goes by columns (i.e. day of week) vs a date range like Range does.
