arrowKey
arrowKey direction
If the global property textArrows is false , the arrowKey command navigates through cards:
arrowKey left = go to previous card
arrowKey right = go to next card
arrowKey up = go forward through recent cards
arrowKey down = go backward through recent cards
If the global property textArrows is true , the arrowKey command navigates through cards unless the insertion point is in a field. Then arrowKey moves the insertion point within the field.
HyperCard sends the arrowKey command to the current card when an arrow key is pressed. The value passed to the parameter variable direction is left , right , up , or down , depending on which arrow key is pressed.
To handle the arrowKey message, use the following form:
on arrowKey whichKey
statements
end arrowKey
In the above form, the parameter variable whichKey is set to a direction .
Placeholders
