A search operation may be initiated either by the application (see TXC.SRCHKEY) or by the user by clicking on the search icon (binoculars) on the toolbar (see TXF_TOOLBAR and TXC.TOOLBARMASK) or by hitting F5 (assuming that TXC.FMAPCTL has been set to forward F5 to the control. The operator can continue searching for additional matches by hitting Ctrl+F (search forwards) or Ctrl+Shift+F (search backwards)..

Currently replace operations can only be initiated by the user, by hitting f6 (again, assuming that that Error! Unknown switch argument. has been set to forward F6 to the control).
