One pair at a time is the default, but a regular-expression group lets you fold several candidates into a single pattern: replacing (apple|pear|grape) with "fruit" handles all three at once. When each term needs a different replacement, order matters — run the terms that do not overlap first, so an earlier result does not get caught by a later rule.
Turn on regular-expression mode and you can target a line break as \n, a tab as \t and a run of whitespace as \s+. To clean up the ragged line breaks in text copied out of a PDF, replace \n with a single space and the paragraphs come back. If you want to keep the blank lines between paragraphs, first swap \n{2,} for a temporary marker, do the cleanup, then restore it.
