If you are visually selecting from the cursor to the end of the line, you will probably hit:

v$

This isn’t always ideal though because the visual selection includes the newline character at the end of the line. If instead you’d like to motion to the last non-blank character on the line you can use the g_ motion. This is great for deleting to the end of the line.

dg_

See :h g_ for more details.
