InDesign’s Text Frame Options dialog box contains a few features/options you may find yourself using often, such as adjusting the column width of your text frame, adding inset spacing, adjusting the frame justification, adjusting your baseline options, and more. There are two ways (I know of) to quickly access the Text Frame Options.

A quick way to access them is to hit Command + B with the frame selected. But a quicker way is to Option + Double Click with either of the Selection tools active.
