hi Marc,
first of all i would like to apologies for so late reply. I was stuck in my semester examinations.
and this time I wanted to come only with some lead, so didn't informed with that.
i was basically talking about all the select tags. See from my research i found that due to some reason keyup and keydown events are not integrating correctly with those tags. And since keypress event don't catch "enter key" press, so it is not functioning.
since i was not able to find a general solution at once, i thought of going through a more specific select tag and solve its issue and then find a general solution. so i started focusing over the "recent_tagle_tag" in "pma_navigation_content". i added many onkeypress/up/down events so that we can bypass the situation where enter key hit is not even recognized.
simplest solution which i found to it was simple writing a onkeydown/up event (not onkeypress) and to determine the enter key hit. Once determined, losing the focus from select tag, simply solves our purpose.
i did this on my local server pma and its working.
please give your comments.
