How can I save a text block in visual mode to a file in Vim?

Question

The title is very descriptive. Just in case, I will give an example:

START BLOCK1 something END BLOCK1  START BLOCK2 something somenthing... END BLOCK2 

1. I select the BLOCK1 in visual mode
2. I yank it by pressing y
3. How can I save the yanked BLOCK1 to some other file?

Answer 1

Select the text you wish to save, in either line visual or block visual mode, and

:w new.txt 

That's what you type, but you won't actually see exactly what's above. When you press :, you'll go to the command line which will automatically get filled in with selection information. It'll look something like this:

:'<,'> 

Just carry on typing the rest (w new.txt) to get

:'<,'>w new.txt 

...and press enter.
