T - Test for pattern. T - Test for pattern. However, any non-alphanumeric character can also be used.
T checks one or more lines to see if they contain a string that matches pattern .
If you do not specify an addresses, T checks only the current line. If you specify one address, T checks that line instead. If you specify two addresses, T checks all the lines between and including those two lines. If the first address comes later in the buffer than the second address, T will begin at the first address and go backwards through the buffer in search of a match for pattern . This is the one case where you can specify a pair of addresses for a FRED command and have the first address come after the second in the buffer.
