jQuery Grid Plugin - jqGrid

Greetings to all!

In first, thanks to Tony for his efforts. jqGrid is very useful in right hands. Sorry for my English.

And thats the question is:

How to transfer ID's of selected rows to PHP – on MouseClickButton, i.e., in jqGrid terms – onSelectRow. 

Here we are, the table, jqGrid ver 3.5:

Fulfilling such things, as popup full-sized images for onMouseOver event, saverow.php - working good (thanks again to Tony and others), and also saverow.php fulfilling task of assigning flag in hidden column – so, after clicking many rows and pushing "Sort selected rows" button – they going first in grid, so user can proof his choice or deselect some, and only then press "Save grid" or some.

But it takes many time – select each row and press Enter. Mayby exist much easier way?

I carefully reading all jqGrid examples and manuals, but cant find solution.

Iis it possible – get selected ID to MySQL DB via PHP – on SelectRow event ? Each row's ID then go to the base, and then "Sort selected rows"  and so on.

Or more useful – get array of selected ID's to the PHP – via assigned button?

I'am not good in AJAX and jQuery, that's why i beg your pardon, and ask to explain in detail, or give example of code.

My current code is:

What i need to do instead alert expression – call AJAX function or function similar - saverow.php, maybe to immediately perform SQL like that:

or store expression in array?

And please, give me some words about selecting rows with holding Shift button. Is that possible?
