If you want to something different, maybe you could add your own text input where the text to search for is entered, and you could write a script to loop though all the items in the list box, and then select the one that matches according to any criteria that you like.

Here are my observations ...
When a listbox has the focus and keys are pressed, the behaviour is to search from the start of the text of each item
When I pressed U, it selected USA; when I pressed U again, it selected UK ... looks like search begins at the current selection.
If you want to something different, maybe you could add your own text input where the text to search for is entered, and you could write a script to loop though all the items in the list box, and then select the one that matches according to any criteria that you like.
I think what suyonob is asking for is that e.g. after pressing U, the list of items available for selection should be reduced to just USA and UK ... you can accomplish this with VisualNEOWin (old NeoBook), but VisualNEOWeb appears to have a defect ... the property named items works fine when hard coded at design time, but if you specify a [variable], it displays one item for each character (I tried it with items separated by commas and \n) ... perhaps Luis can investigate and tell us if this is a defect or not.
So, if it was possible to dynamically change the list of items, it would be possible to do what suyonob is asking for.
Also, I was not clear what suyonob meant when (s)he posted that ...
i have a table that contain 7 records
... what kind of Table ? (on a database on the server or a neoTable )

The ListExample.neoapp in the Sample Apps included with VisualNEO Web shows how the contents of a listbox can be changed dynamically.
I don't think there is a defect in VisualNEO Web? It's more that things work differently in a browser and so every object is unlikely to work identically as in VisualNEO Win.

I have attached a tiny app (the scripts are in page-enter and change of the text input) that does what I was describing in general terms, maybe someone will find it useful?

Didn't think to look at samples ... ListBox items are stored as array items ... thanks for the tip.
However, when I typed u, I got a whole bunch of items that contained (not just started with) the letter u ... it was only when I followed through with the letter k that it showed Ukraine.
It might be better to search the array items for a match starting at position 0 ... e.g.
If [foundIndex] = 0
Thanks again.

You are very welcome, I love solving problems.
About your comment, what works best depends?
Having it search so that the user types any part of the name of a country, was intentional. With a list of countries like this, it is possible for a user to not know the first letter that they need to type. For example, if I want to find South Korea, do I start typing "Korea" or "South"?
With the search in my tiny app, it doesn't matter which, I will quickly find the country, which (I think) is better.
I agree that in some cases your suggestion of only searching from the start of the words in the list would be precisely what is required.

Just note linstboxes behaviour is enterely controled by the web browser.
I mean, it's a web browser built-in object.
