[Zope] documentation about the ":method"

[Manuel Spuhler]

Hello Martin,

quoted from http://www.plope.com/Books/2_7Edition/ScriptingZope.stx
"action
Appends the attribute value to the original form action of the form.
This is mostly useful for the case in which you have multiple submit
buttons on one form. Each button can be assigned to a script that gets
called when that button is clicked to submit the form. A synonym for
action is method."

so basically, I interpretted it like: 'foo:action' == 'foo:method',
but it's unclear. Thanks for your precision.

Manuel
