If you don't mind using a little JavaScript you can test for which button
should fire when enter is pressed. How I would do it is to first add a hidden
field and call it "buttonClicked". Now, in the text field where you would like
a button to fire if enter is pressed, at this to the tag:
onkeyup="checkKey(this,event)". For the JavaScript portion of it, do this:
function checkKey(element,evt) {
var buttonClicked=""
if(evt.keyCode=13) {
if(element.name="field1") {
buttonClicked="button1"
} else if(element.name=="field2") {
buttonClicked="button2"
}
if(buttonClicked) {
document.formName.buttonClicked.value=buttonClicked
document.formName.submit()
}
}
}
Hope that helps!
Take care,
Floyd
