fieldtrip is a combination of the plugins submode and sideways.
By pressing fieldtrip_start_map, vim enters a sideways submode. h and l
are then temporarily mapped to :SidewaysLeft and :SidewaysRight, h and l
will cycle through the fields.
d will delete the motion <Plug>SidewaysArgumentTextobjA, x deletes the
"inner" variant <Plug>SidewaysArgumentTextobjI. By default, <esc> exits
the submode. Consult the submode doc for more options, especially for
preventing the automatic exit after 'timeout' ms of idling.
Change g:fieldtrip_start_map to the key sequence you want to use to enter the
submode.
Read the help file for the variable names used to map the submode actions.
