Simultaneous editing
In human–computer interaction, simultaneous editing is an end-user development technique allowing a single user to make multiple simultaneous edits of text in a multiple selection at once through direct manipulation. Multiple selections and cursors are typically created by using a keyboard shortcut to select repeated instances of the same text or text fragments surrounded by the same delimiters, by using a search feature to select all instances of a search term, by selecting the same column in multiple lines, or by selecting text or cursor positions with a mouse.
