Menu(メニュー):

Select(選択) ‣ Select Random(ランダム選択)

Adds random items to the selection.

Ratio(比率)

The ratio of items that should end up selected, e.g. 0.5 to select half of all items (that are not hidden).

Note that the existing selection is ignored: if half of the items are already selected, setting Ratio to 0.1 won't deselect anything, nor will it select 10% of the unselected items. Instead, it always picks 10% of all visible items and adds them to the selection.

Random Seed(ランダムシード)

A number that influences which specific items get picked.

Action(アクション)

Deselect(選択解除):
