Selection

A single click will select a value. The arrow keys, (⭠ ⭣ ⭡ ⭢) or (h j k l for vim folks) will change the selection relative to the currently selected value. Relative selection is based on the viewer.

Selection is an important concept in the Portal UI since it is the basis for a lot of the other concepts.

Multi-Select

To select multiple values, hold down either ⌘ or alt and single click a value. To un-select a value, simply click it again while holding down the multi-select key. The order of selection is important to the application of commands.
