Sioyek Tutorial

Features

Quick Open

recent_docs.mp4

You can quickly search and open any file you have previously interacted with using sioyek.

Table of Contents

toc.mp4

You can search and jump to table of contents entries.

Smart Jump

jump.mp4

You can jump to any referenced figure or bibliography item even if the PDF file doesn't provide links. You can also search the names of bibliography items in google scholar/libgen by middle clicking/shift+middle clicking on their name.

Overview

overview.mp4

You can open a quick overview of figures/references/tables/etc. by right clicking on them (Like Smart Jump, this feature works even if the document doesn't provide links).

Mark

mark.mp4

Sometimes when reading a document you need to go back a few pages (perhaps to view a definition or something) and quickly jump back to where you were. You can achieve this by using marks. Marks are named locations within a PDF file (each mark has a single character name for example 'a' or 'm') which you can quickly jump to using their name. In the aforementioned example, before going back to the definition you mark your location and later jump back to the mark by invoking its name. Lower case marks are local to the document and upper case marks are global (this should be very familiar to you if you have used vim).

Bookmarks

bookmarks.mp4

Bookmarks are similar to marks except they are named by a text string and they are all global.

Highlights

highlights.mp4

Highlight text using different kinds of highlights. You can search among all the highlights.

Portals (this feature is most useful for users with multiple monitors)

portal.mp4

Suppose you are reading a paragraph which references a figure which is not very close to the current location. Jumping back and forth between the current paragraph and the figure can be very annoying. Using portals, you can link the paragraph's location to the figure's location. Sioyek shows the closest portal destination in a separate window (which is usually placed on a second monitor). This window is automatically updated to show the closest portal destination as the user navigates the document.

Configuration

config.mp4

You can customize all key bindings and some UI elements by editing keys_user.config and prefs_user.config. The default configurations are in keys.config and prefs.config.
