onselectstartNN n/a IE 4 DOM n/a  

Bubbles: Yes; Cancelable: Yes  

Fires immediately after the user begins dragging a selection on a body element or form control text. If the selection extends across multiple elements, only one event fires, and its target remains the element where the selection began. Canceling this event in the <body> tag (onselectstart="return false") can prevent undesirable and inadvertent user selection and scrolling interaction.

 
Typical Targets

All rendered elements.
