Search for NON-matching lines. ^E or * Search multiple files (pass thru END OF FILE). ^F or @ Start search at FIRST file (for /) or last file (for ?). ^K Highlight matches, but don't move (KEEP position). ^R Don't use REGULAR EXPRESSIONS. --------------------------------------------------------------------------- JJUUMMPPIINNGG g < ESC-< * Go to first line in file (or line _N).

ESC-^B _<_c_1_> _<_c_2_> * Find open bracket _<_c_1_> --------------------------------------------------- Each "find close bracket" command goes forward to the close bracket matching the (_N-th) open bracket in the top line. Each "find open bracket" command goes backward to the open bracket matching the (_N-th) close bracket in the bottom line. m_<_l_e_t_t_e_r_> Mark the current position with <letter>. '_<_l_e_t_t_e_r_> Go to a previously marked position. '' Go to the previous position. ^X^X Same as '. --------------------------------------------------- A mark is any upper-case or lower-case letter.
