In human–computer interaction, simultaneous editing is an end-user development technique allowing a 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. The Lapis experimental web browser and text editor is also able to infer selections based on concept learning from positive and negative examples given by the user during a process known as selection guessing.
Tools for data wrangling (mass reformatting) also sometimes include commands for simultaneous editing of all data in a column or category.
