My favorite shortcut in IE from 10 years ago is Alt + Shift + S, which submits the form you're currently in.
On Chrome/Windows, Alt + Shift + S has started working recently (though it displays different behavior by submitting "a form" which may or may not be the form you're on). Does anyone know if there is a "submit this form" or "submit a form" keyboard shortcut for Chrome/OS X, and if not, if it is possible to create such a form?
execute javascript
via AppleScript. Does anyone better at JS know how to submit the current form?
