              corresponding to the letters, *, in another string preference which  specifies  the
              url, search_url_*.

              For example,

       •      search_url_g https://www.duckduckgo.com/search?q=

       •      middle_click_search_engine g

              Will use the duckduckgo address for middle click search.

       shift_middle_click_search_engine string

              looks better but may increase power consumption.

       wheel_zoom_on_cursor boolean

              Normally mouse wheel zooms in on the middle of the screen, but if this is set to 1,
              we zoom in on the cursor.

       linear_filter boolean

              Apply  linear texture filtering by passing GL_LINEAR to glTexParameteri. This means
              that for a pixture being textured, we use the weighted average of the four  texture
              elements closest to its center.

              command.

              If  this  is  not  set,  then we use the full size of the first screen if there are
              multiple monitors, otherwise we use half of the width of the screen and  the  whole

       helper_window_size ivec[2]

              Default size (in width and height) of the helper window when it is opened.

              If not set, use the full size of the second screen if there are multiple  monitors,
              otherwise use half of the width of the first screen and the whole height.

              If not set, uses (0, 0).

       fit_page_to_width_ratio float

              Ratio  of page width to use for fit_to_page_width_ratio command. A value of 1 would
              use the whole window width for the page.

              If set, we initially collapse table of content entries.

       ruler_mode boolean

              If set, we highlight the current line in visual_scroll_mode by  masking  above  and

              toggle_fastread) by default queries a url for information about which characters of
              each  word  on the page to highlight. An implementation of such a server based on a
              language             model             is              available              here:
              https://github.com/ahrm/sioyek/blob/main/scripts/summary_highlight_server.py.

              By default, both this script and sioyek will bind to localhost:5000.

       text_summary_should_refine boolean

              Language  model  option  for  the  fastread  server  program.  If  1,  then prevent
              highlights in the  middle  of  words  by  always  highlighting  starting  from  the
              beginning of the word until the first mispredicted character.

       text_summary_should_fill boolean

              Language  model  option  for  the fastread server program. If 1, then highlight the
              entire word when over 50% of it is highlighted.

       text_summary_context_size integer

              Context size to use on the fastread server. Number of  characters  in  context  for

       use_heuristic_if_text_summary_not_available boolean

              Use  heuristic  if  text  summary  url  does  not  return highlights. The heuristic
              involves choosing ceiling(length*0.3) characters of every word to emphasize.

       papers_folder_path string

              A directory which sioyek watches for new papers. If  a  new  paper  added  to  this
              directory  while  we are creating a portal from another document, this new document
              will automatically be used as the destination of the portal.

       enable_experimental_features boolean

              Enable possibly unstable experimental features

       create_table_of_contents_if_not_exists boolean

              Automatically create a table of contents for the document  if  it  doesn't  already
              have one.

       max_created_toc_size integer

              Limits the maximum size of created table of contents.

       force_custom_line_algorithm boolean

              Use custom algorithm based on pixmaps to compute rectangles around the lines of the
              document.

       overview_size fvec[2]

              Size, width and height, of the overview window. The overview window is triggered by
              right clicking on an internal link, or hovering if hover_overview is set to 1.

       overview_offset fvec[2]

              Offset of the overview window as floats from the center of the page.

       ignore_whitespace_in_presentation_mode boolean

              Always use fit_to_page_smart (ignoring whitespace) in presentation view.

       exact_highlight_select boolean

              If  set to 0, then in word select mode, select the whole word even if the cursor is
              only partially on the word. If set to 1, then select the word only if the range  of
              the cursor's selection fully includes the word.

       show_doc_path boolean

              If set to 0, then only show the filename in the dialog to choose to open a previous
              doc (open_prev_doc). If 1, then show the entire file path.

       fastread_opacity float

              Opacity of the dimmed portion of words in fastread mode.

       highlight_color_* color_3

              Color of the highlight color bound to symbol * (should be one character).

       should_warn_about_user_key_override boolean

              If set to 0, then don't warn the user about key definition overrides when  the  two
              definitions  are  in  different  files. If set to 1, then always warn the user when
              keys are overridden.

       single_click_selects_words boolean

              If set to 0, then single clicks select words and double clicks allow  selection  of
              arbitrary  ranges  of  characters. If set to 1, then double clicks select words and
              single clicks allow selection of arbitrary ranges of characters.

       highlight_middle_click boolean

              If set to 1, then middle clicks add a highlight with select_highlight_type  when  a
              selection  is  active  and  no preview is open. If set to 0, a smart jump is always
              attempted.

       super_fast_search boolean

              If set to 0, search is performed by the mupdf backend. If set to 1,  a  super  fast
              search index is used instead. This leads to a slight increase in memory.

       case_sensitive_search boolean

              If  set  to  1, search and regex_search are case-sensitive. If set to 0, search and
              regex search are case-insensitive.
