arrowKeyarrowKey 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. Examples-- Option + left and right arrow keys go to prev and next marked card on arrowKey whichKey if the optionKey is down then if whichKey is "left" then go previous marked card else if whichKey is "right" then go next marked card end if else pass arrowKey -- let the other arrowKey messages pass end arrowKey
