Vim - delete until (inclusive) character in multiple lines

Try with this: d%.

The d is for delete and the % moves between braces.

This should work:

d}

This deletes one paragraph forward.

d/}/e

does the job.

d/} deletes until the } but adding the /e flag moves the cursor on the last char of the match, effectively deleting everything between the cursor and the }, inclusive.

Using visual selection works too, in a slightly more intuitive way:

v/}<CR>d
