CommandButton – PB Docs 2017

CommandButtons are used to carry out actions. For example, you
can use an OK button to confirm a deletion or a Cancel button to
cancel a requested deletion. If there are many related CommandButtons,
place them along the right side of the window; otherwise, place them
along the bottom of the window.

You cannot change the color or alignment of text in a
CommandButton.

If clicking the button opens a window that requires user
interaction before any other action takes place, use ellipsis points
in the button text; for example, “Print…”.
