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.
