another option is to use the tag "command" like this way:
<command name="cmdGravar"
onselect="classroot.pnlButtons.btnGravar.Execute()"
key="['Control','Alt', 'S']" />
"gravar" on my country means "save". This code tell laszlo to listen
for the combination of ctrl+alt+S to execute the action of the
onselect. In that case, execute my button named btnGravar.
but....
doesnt matter if u use this aproache or the one benjamin show, the
browser always rules what keys u can use or not. This, in my opinion is
a baaad bad thing. ;)
i mean... u cant use F5 to nothing on IE. If u have Google bar
installed on your firefox (like me) u cant use ctrl+alt+G coz he
intercept it. But, google bar of internet explorer dont use such
combination.
there are another combinations that work on one both not on another...
(and i am talking only about IE and firefox.... imagine if we put all
together.. netscape, opera, links (lol )
hope it helps.
