<<button>> macro creates a button, a special type of link that, when clicked, sets the data entered into other form macros in the passage (
<<checkbox>>), and moves to another passage.
<<button>> macro should be provided with the familiar link syntax:
<<button [[displayed text|passage name]]>>
The resulting button behaves identically to a normal link, but, when clicked, additionally causes the data entered into
<<checkbox>> macros to be placed in the variables.
For instance, if the macro
<<textinput $FoodName>> appears in the same passage with a
<<button>>, and the text "pretzels" has been entered into the input box, then clicking the button will, in addition to changing passages, run the equivalent of
<<set $FoodName to "pretzels">>.
