Most callback handlers in the Raw XML API Dump http://api.jquery.com/api/ are documented as handler(eventObject). However some are only documented as handler that should probably be documented as handler(eventObject). This seems to be the case for the following functions: off, on, undelegate, delegate, live, one.

Correctly documented function arguments allow tools like http://marketplace.eclipse.org/content/jsdt-jquery to correctly identify function arguments as events and present proposals accordingly.

Functions with handlers documented as handler(eventObject): toggle, focusout, focusin, keydown, scroll, resize, keyup, keypress, submit, select, change, blur, focus, mousemove, mouseleave, mouseenter, mouseout, mouseover, dblclick, click, mouseup, mousedown, error, unload, load, unbind, bind.
