[FONT=Verdana]In an alphabetically sorted array, I want to jump from one letter to another.[/FONT]
[FONT=Verdana]So, when I’m with a word beginning with “a”, I want to jump to the next item beginning with “b”…etc[/FONT]
[FONT=Verdana] [/FONT]
[FONT=Verdana]I’ve set up this simple script, which simply look at the first character of the current item, then loop in the (sorted) array until it finds a different first character…[/FONT]
[FONT=Verdana]It works very well…when descending![/FONT]
[FONT=Verdana]But when ascending, the script sees that there is character change…but this is not the first item beginning with that letter…but the last one (since we are coming from bottom to top)[/FONT]
[FONT=Verdana]And of course I would like the script to give me the very first item beginning with a new letter.[/FONT]
[FONT=Verdana] [/FONT]
[FONT=Verdana](So, to summarize, I want to browse an array alphabetically, up & down, so that each time I press on the UP arrow key, I go up in the alphabet….and when I press the DOWN arrow key, I go down in the alphabet)[/FONT]
[FONT=Verdana] [/FONT]
[FONT=Verdana]Would you please have an elegant way to do this?[/FONT]
[FONT=Verdana]Thanks very much ;-)[/FONT]
