Hello Tony Jollans,
Many thanks for taking the trouble to reply.
In notes made from a text book “strikethrough” can be just one method to show how some parts of the text have changed with the issue of a new edition
of the text book, particularly when you sometimes wish to keep the old version of some text rather than simply update it. Then, if a further version of the text book comes out, or amendments need to be made from some other source, colour-coding the “strikethrough”
is one way to show which of the source material is responsible for that particular change.
You make reference to an interesting procedure, namely:
Overlay text with struckthrough spaces, and then format them with selected colour.
I have looked at the web page you linked. While not unwilling to plough my way though relevant text, the web page unfortunately seems somewhat complicated
if the idea of it were only to provide simple instructions for doing the above procedure.
Are there perhaps instructions available to explain a little more simply, just the above procedure, rather than one that seems to cover most aspects
of a somewhat wider area of knowledge?
Regards.
