How to very simply and easily replace blocks of text?

[Bruno Vincent]

This questions is so stupid it’s ridiculous…but I couldn’t find any easy answer on Google…so here it is:

I have a list:

1
2
3
a
b
c

How can I replace

1
2
3

With:

4
5
6

So the result is:

a
b
c
4
5
6

Thanks

@Bruno-Vincent

do you look for some automatism or are you looking for column mode?
If the first is the case we need to have more details about the real data it the latter
is the case, click with the mouse to the first position, press SHIFT+ALT and while still pressing
click with the mouse the end position. Then do simple CTRL+X and CTRL+V
