Short answer 1: It is a lot of code! :) Short answer 2: It holds a lot of the functions that FIELD, AREA, TEXT, H1, H2, etc. need. Longer answer: You can build VID programs without knowing about it. ctx-text is an object! which holds some words, some objects and a lot of functions. All these things are grouped in the object ctx-text because they relate to text handling. For example, these functions and objects work together to give the ability to copy text from a View window to the clipboard. Like this: view layout [text {Highlight this text with you mouse and copy it to the clipboard using ctrl-c.}] If I deliberately "cut the link" to ctx-text - see what happens: view layout [text "Try to copy this text now." with [feel: none]] Normally this prints true: layout [text-object: text "Some text"] print same? text-object/feel ctx-text/swipe So the summary is VID styles use ctx-text to handle keystrokes, and other text handling.
